Add support for the MT6331 PMIC with MT6332 Companion PMIC, found
in MT6795 Helio X10 smartphone platforms.
This combo has support for multiple devices but, for a start,
only the following have been implemented:
- Regulators (two instances, one in MT6331, one in MT6332)
- RTC (MT6331)
- Keys (MT6331)
- Interrupts (MT6331 also dispatches MT6332's interrupts)
There's more to be implemented, especially for MT6332, which
will come at a later stage.

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.
