a4872e80ce mfd: mt6397: Extract IRQ related code from core driver
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.

6df8dd5c18 mfd: Add support for the MediaTek MT6397 PMIC
This adds support for the MediaTek MT6397 PMIC. This is a
multifunction device with the following sub modules:

- Regulator
- RTC
- Audio codec
- GPIO
- Clock

It is interfaced to the host controller using SPI interface by a proprietary
hardware called PMIC wrapper or pwrap. MT6397 MFD is a child device of the
pwrap.
