Rename the SPMI device helper which is used to lookup a device from its
OF node as spmi_find_device_by_of_node() so that it reflects the
implementation and matches how other helpers like this are named.
This will specifically make it more clear that this is a lookup function
which returns a reference counted structure.

Commit 9e86b2ad4c11 changed the channel used for HPDET detection
(headphones vs lineout detection) from being hardcoded to
ARIZONA_ACCDET_MODE_HPL (HP left channel) to it being configurable
through arizona_pdata.hpdet_channel the DT/OF parsing added for
filling arizona_pdata on devicetree platforms ensures that
arizona_pdata.hpdet_channel gets set to ARIZONA_ACCDET_MODE_HPL
when not specified in the devicetree-node.
But on ACPI platforms where arizona_pdata is filled by
arizona_spi_acpi_probe() arizona_pdata.hpdet_channel was not
getting set, causing it to default to 0 aka ARIZONA_ACCDET_MODE_MIC.
This causes headphones to get misdetected as line-out on some models.
Fix this by setting hpdet_channel = ARIZONA_ACCDET_MODE_HPL.

The Qualcomm SPMI PMIC revid implementation is broken in multiple ways.
First, it assumes that just because the sibling base device has been
registered that means that it is also bound to a driver, which may not
be the case (e.g. due to probe deferral or asynchronous probe). This
could trigger a NULL-pointer dereference when attempting to access the
driver data of the unbound device.
Second, it accesses driver data of a sibling device directly and without
any locking, which means that the driver data may be freed while it is
being accessed (e.g. on driver unbind).
Third, it leaks a struct device reference to the sibling device which is
looked up using the spmi_device_from_of() every time a function (child)
device is calling the revid function (e.g. on probe).
Fix this mess by reimplementing the revid lookup so that it is done only
at probe of the PMIC device; the base device fetches the revid info from
the hardware, while any secondary SPMI device fetches the information
from the base device and caches it so that it can be accessed safely
from its children. If the base device has not been probed yet then probe
of a secondary device is deferred.

The Qualcomm SPMI PMIC revid implementation is broken in multiple ways.
First, it totally ignores struct device_node reference counting and
leaks references to the parent bus node as well as each child it
iterates over using an open-coded for_each_child_of_node().
Second, it leaks references to each spmi device on the bus that it
iterates over by failing to drop the reference taken by the
spmi_device_from_of() helper.
Fix the struct device_node leaks by reimplementing the lookup using
for_each_child_of_node() and adding the missing reference count
decrements. Fix the sibling struct device leaks by dropping the
unnecessary lookups of devices with the wrong USID.
Note that this still leaves one struct device reference leak in case a
base device is found but it is not the parent of the device used for the
lookup. This will be addressed in a follow-on patch.

`strncpy` is deprecated for use on NUL-terminated destination strings
[1] and as such we should prefer more robust and less ambiguous string
interfaces.
We expect project_name to be NUL-terminated based on its use with
pr_info:
| pr_info("PRCMU firmware: %s(%d), version %d.%d.%d\n",
| fw_info.version.project_name,
| fw_info.version.project,
| fw_info.version.api_version,
| fw_info.version.func_version,
| fw_info.version.errata);
Moreover, NUL-padding does not seem to be needed.
Considering the above, a suitable replacement is `strscpy` [2] due to
the fact that it guarantees NUL-termination on the destination buffer
without unnecessarily NUL-padding.
Let's also change `PRCMU_FW_PROJECT_NAME_LEN` to just
sizeof(fw_info.version.project_name) as this is more idiomatic strscpy
usage.

The maple tree register cache is based on a much more modern data structure
than the rbtree cache and makes optimisation choices which are probably
more appropriate for modern systems than those made by the rbtree cache. In
v6.5 it has also acquired the ability to generate multi-register writes in
sync operations, bringing performance up to parity with the rbtree cache
there.

At the moment we allow the AXP15060 and the AXP806 PMICs to omit the
interrupt line to the SoC, and we skip registering the PEK (power key)
driver in this case, since that crashes when no IRQ is described in the
DT node.
The IRQ pin potentially not being connected to anything does affect more
PMICs, though, and the PEK driver is not the only one requiring an
interrupt: at least the AC power supply driver crashes in a similar
fashion.
Generalise the handling of AXP MFD devices when the platform tables
describe no interrupt, by allowing each device to specify an alternative
MFD list for this case. If no specific alternative is specified, we go
with the safe default of "just the regulators", which matches the current
situation.
This enables new devices using the AXP313a PMIC, but not connecting the
IRQ pin.

Constify .data in OF table and {palmas,tps65917}_irq_chip and replace
the variable *features->features in struct palmas_driver_data and
drop the {palmas,tps659038}_features variables and use their values
directly in the named initialization.

The loop searching for a matching device based on its compatible
string is aborted when a matching disabled device is found.
This abort prevents to add devices as soon as one disabled device
is found.
Continue searching for an other device instead of aborting on the
first disabled one fixes the issue.

The code was accidentally mixing new and old style macros, update the
macros used to remove an unused function warning whilst building with
no PM enabled in the config.
