A platform_driver does not need to set an owner, it will be populated by the
driver core.

commit 2243a87d90b42eb38bc281957df3e57c712b5e56
"pinctrl: avoid duplicated calling enable_pinmux_setting for a pin"
removed the .disable callback from the struct pinmux_ops,
making the .enable() callback the only remaining callback.
However .enable() is a bad name as it seems to imply that a
muxing can also be disabled. Rename the callback to .set_mux()
and also take this opportunity to clean out any remaining
mentions of .disable() from the documentation.

Palmas devices do not support the default bias configuration
and hence removing this option from valid pin config parameters.

Recent movement of all configurations of pin in the single call of
pin_config_set(), it is aborting configuration if BIAS_PULL_PIN_DEFAULT
is selected as return of configuration.
The original idea was to just avoid any update on register for pull up/down
configuration if this option is selected.
Fixing this by just bypassing any register update for BIAS_PULL_PIN_DEFAULT
and continuing the remaining configuration.

Palmas pinmux and pin configuration support the single pin level
configuration in place of pin group.
Hence it is only require to pin_config_{set|get} and do not require
pin_config_group_{set|get}. As core framework already check for
require APIs availability, it is not require to implement as dummy
for non-require ops and so removing it.

When setting pin configuration in the pinctrl framework, pin_config_set() or
pin_config_group_set() is called in a loop to set one configuration at a time
for the specified pin or group.
This patch 1) removes the loop and 2) changes the API to pass the whole pin
config array to the driver. It is now up to the driver to loop through the
configs. This allows the driver to potentially combine configs and reduce the
number of writes to pin config registers.
All c files changed have been build-tested to verify the change compiles and
that the corresponding .o is successfully generated.

Add support to pass the config type like GROUP or PIN when using
the utils or generic pin configuration APIs. This will make the
APIs more generic.
Added additional inline APIs such that it can be use directly as
callback for the pinctrl_ops.
Changes from V1:
- Remove separate implementation for pins and group for
pinctrl_utils_dt_free_map and improve this function
to support both i.e. PINS and GROUPs.

TI Palmas series Power Management IC have multiple pins which can be
configured for different functionality. This pins can be configured
for different function. Also their properties like pull up/down,
open drain enable/disable are configurable.
Add support for pincontrol driver Palmas series device like TPS65913,
TPS80036. The driver supports to be register from DT only.
Changes from V1:
- Add generic property for pins and functions in pinconf-generic.
- Add APIs to map the DT and subnode.
- Move common utils APIs to the pinctrl-utils from this file.
- Update the binding document accordingly.
Changes from V2:
- Add ack by Lee.
- Correct the binding docs.
