This series adds support for the 15-bit AUXADC hardware block found on
the MediaTek mt6323 PMIC.
The previous version of the series for all AUXADC, EFUSE and thermal
drivers was split after Krzysztof's comment [1].
Tested on the MediaTek mt6572 and mt8163 SoCs (Ben), both paired with a
mt6323.
The other parts (EFUSE and thermal) will probably be sent next week.

Tested-by: Ben Grisdale <bengris32@protonmail.ch> # Amazon Echo Dot (2nd Generation)

Changes after split:
- dt-bindings: Change 'MT63xx' to 'MT6350 series and similar' (Jonathan)
- AUXADC driver:
- Add missing headers (Andy)
- Fix AUXADC_TRIM_CH* values (Andy)
- Rename masks to include their register name (Jonathan)
- Fix formatting (Andy, Jonathan)
- Replace channel address with actual register value (Jonathan), align the table
- Replace IIO_TEMP with IIO_VOLTAGE, since the actual output is still mV, not mC
- Rename constants to match their registers (Jonathan)
- Remove 'if/else if/else' in the mt6323_auxadc_read_raw (Andy)
- Add comments for fsleep, ADC range and resolution (Andy, Jonathan)
- Remove useless error messages (Andy)
- Maintainers:
- Explicitly include mt6323 in the name (Jonathan)
- Squash with AUXADC driver commit (Krzysztof)
- Set status back to 'Maintained'
- Link to a previous series: https://patch.msgid.link/20260512-mt6323-v2-0-3efcba579e8...
