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 support for the regulators found in MT6331 and MT6332
main/companion PMICs.

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

This series depends on another two series series [1], [2] named
"MediaTek Helio X10 MT6795 - MT6331/6332 PMIC Wrapper" and
"MediaTek Helio X10 MT6795 - MT6331/6332 PMIC MFD integration"

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

Changes in v2:
 - Refactored description in dt-bindings
 - Simplified get_status() function and removed callback
   where not needed
 - Simplified set_mode()/get_mode() functions and removed
   callback where not needed
 - Added new regulator_ops for no_qi (no .get_status) and
   for no_ms (no .{get, set}_mode)
 - Fixed vsel mask on some regulators and removed pattern of
   repeated voltage entries present in some voltage tables,
   avoiding to set higher bits for safety
 - Reordered regulators (and some formatting fixes) in
   mt6331-regulator.c in per-type alphabetic order
