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.
