mfd: Add support for the MediaTek MT6359 PMIC 



This adds support for the MediaTek MT6359 PMIC. This is a
multifunction device with the following sub modules:

- Codec
- Interrupt
- Regulator
- RTC

It is interfaced to the host controller using SPI interface
by a proprietary hardware called PMIC wrapper or pwrap.
MT6359 MFD is a child device of the pwrap.
