In an effort to give some love to the apparently forgotten MT6795 SoC,
I am upstreaming more components that are necessary to support platforms
powered by this one apart from a simple boot to serial console.

This series adds the necessary headers and support for the MT6331 with
MT6332 companion PMIC in the mt6397 MFD driver, along with some basic
devices.

Adding support to each driver in each subsystem will be done in different
patch series as to avoid spamming uninteresting patches to maintainers.

This series depends on another series [1] named
"MediaTek Helio X10 MT6795 - MT6331/6332 PMIC Wrapper", meaning that
even if this builds without, the changes in said series are necessary
to actually use these PMICs.

Tested on a MT6795 Sony Xperia M5 (codename "Holly") smartphone.
