commit 668f69a5f863b877bc3ae129efe9a80b6f055141 upstream.
The number of policies are 10, so can't be supported by the bitmap size
of u8.
Even though there are no platfoms with these many policies, but
for correctness increase to u32.

[ Upstream commit 396ee4d0cd52c13b3f6421b8d324d65da5e7e409 ]
int3400 only pushes the UUID into the firmware when the mode is flipped
to "enable". The current code only exposes the mode flag if the firmware
supports the PASSIVE_1 UUID, which not all machines do. Remove the
restriction.

The thermal code uses int, long and unsigned long for temperatures
in different places.
Using an unsigned type limits the thermal framework to positive
temperatures without need. Also several drivers currently will report
temperatures near UINT_MAX for temperatures below 0°C. This will probably
immediately shut the machine down due to overtemperature if started below
0°C.
'long' is 64bit on several architectures. This is not needed since INT_MAX °mC
is above the melting point of all known materials.
Consistently use a plain 'int' for temperatures throughout the thermal code and
the drivers. This only changes the places in the drivers where the temperature
is passed around as pointer, when drivers internally use another type this is
not changed.

It is possible that _ART/_TRT tables are missing or have errors.
Ignore those failures, as INT3400 thermal zone is still required
for _OSC or mode switch.

INT3400 currently supports only one policy, which can't be changed.
This change exports all available policies (uuids) to user space and
allow this to be changed.
It introduces an attribute group uuids in INT3400 platform driver.
There are two attributes exposed:
- available_uuids
- current_uuid
User space can set current_uuid via this interface to one of the
available uuids. The uuid change is communicated to firmware, only
when the current zone mode is changed to "enabled". So the ideal
sequence should be
- set INT3400 zone mode to "disabled"
- change current_uuid
- set INT3400 zone mode to "enabled"

ACPI _TRT and _ART parsing code has been moved to acpi_thermal_rel such
that it can be used by other devices in the future. Use the parsing APIs
in acpi_thermal_rel.c instead.

enumerate the other int340x thermal components shown in _ART/_TRT.
