regulator: mt6358: Add missing regulators for MT6366
When support for the MT6366 PMIC regulators was added, it was assumed
that it had the same functionality as MT6358. In reality there are
differences. A few regulators have different ranges, or were renamed
and repurposed, or removed altogether.

Add the 3 regulators that were missing from the original submission.
These are added for completeness. VSRAM_CORE is not used in existing
projects. VM18 and VMDDR feed DRAM related consumers, and are not used
in-kernel.

regulator: mt6358: Add output voltage fine tuning to fixed regulators
The "fixed" LDO regulators found on the MT6358 and MT6366 PMICs have
either no voltage selection register, or only one valid setting.
However these do have a fine voltage calibration setting that can
slightly boost the output voltage from 0 mV to 100 mV, in 10 mV
increments.

Add support for this by changing these into linear range regulators.
Some register definitions that are missing are also added.

c47383f849 mfd: Add support for the MediaTek MT6366 PMIC
This adds support for the MediaTek MT6366 PMIC. This is a
multifunction device with the following sub modules:

- Regulator
- RTC
- Codec
- Interrupt

It is interfaced to the host controller using SPI interface
by a proprietary hardware called PMIC wrapper or pwrap.
MT6366 MFD is a child device of the pwrap.

9a2601ebc2 mfd: mt6397: Add MT6358 register definitions for power key
To support power/home key detection, add definitions for
two more MT6358 PMIC registers:

- TOPSTATUS: homekey and powerkey debounce status
- TOP_RST_MISC: controls homekey,powerkey long press reset time
