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.

This add support for the MediaTek MT6358 RTC. Driver using
compatible data to store different RTC_WRTGR address offset.
This replace RTC_WRTGR to RTC_WRTGR_MT6323 in mt6323-poweroff
driver which only needed by armv7 CPU without ATF.

Some pmics don't need backup interrupt settings, so we change to use
pm notifier for the pmics which are necessary to store settings.

Alarm registers high byte was reserved for other functions.
This add mask in alarm registers operation functions.
This also fix error condition in interrupt handler.

In order to support different types of irq design, we decide to add
separate irq drivers for different design and keep mt6397 mfd core
simple and reusable to all generations of PMICs so far.
