[PATCH v3 0/8] Add support for MT6331 and MT6332 LEDs

[AngeloGioacchino Del Regno]

Changes in v3:
 - Rebase over next-20230601
 - Beautified ISINK_CON0 comment
 - Added binding for mediatek,is-wled property

Changes in v2:
 - Rebase over next-20230412

NOTE: Since v1 of this series was sent in Semptember 2022 and got
ignored for *7 months* with no feedback, I'm retrying the upstreaming
of this same series.
There are no changes, if not just a simple rebase and another test
run on the same hardware.


MT6323 is not the only PMIC that has a LEDs controller IP and it was
found that the others do have a compatible register layout, except
for some register offsets.
The logic contained in this driver can be totally reused for other
PMICs as well, so I can't see any reason to keep this specific to
the MT6323 part.

This series brings meaningful platform data to this driver, giving
it flexibility and adding support for LED controllers found in the
MT6331 and MT6332 PMICs.

Tested on MT6795 Sony Xperia M5 smartphone.
