regulator: mt6315: add regulator supplies

Chen-Yu Tsai <wenst@chromium.org> says:

This series is part of a broader collection of regulator related
cleanups for MediaTek Chromebooks. This one covers the MT6315 PMIC.

Patch 1 adds the names of the power supply inputs to the binding.

Patch 2 adds the supply names from the DT binding change in patch 1
to the regulator descriptions in the driver. This patch has a
checkpatch.pl warnings, but I wonder if it's because the context size
for checking complex macros is not large enough.

Device tree changes will be sent separately. The goal is to get the
regulator tree as complete as possible. This includes adding supply
names to other regulator DT bindings, and adding all the supply links
to the existing DTs.
