Add a new regulator driver for MT6359P and similar PMIC chips.

The MT6359P is a eco version for MT6359 regulator. For the MT8391
platform, we use the MT6359P (MT6365) as the main PMIC. The MT6359 and
MT6359P have different register maps. Therefore, on the MT8391 platform,
we only provide support for the MT6359P. If support for the MT6359 PMIC
it can be added later.

AXP PMICs have a pin which can either report the USB VBUS state, or
driving a regulator that supplies USB VBUS. Add a regulator driver for
controlling this pin. The selection between input and output is done via
the x-powers,drive-vbus-en pin on the PMIC (parent) node.

Tom Rini <trini@konsulko.com> says:

This series switches to always using $(PHASE_) in Makefiles when
building rather than $(PHASE_) or $(XPL_). It also starts on documenting
this part of the build, but as a follow-up we need to rename
doc/develop/spl.rst and expand on explaining things a bit.

It is confusing to have both "$(PHASE_)" and "$(XPL_)" be used in our
Makefiles as part of the macros to determine when to do something in our
Makefiles based on what phase of the build we are in. For consistency,
bring this down to a single macro and use "$(PHASE_)" only.

Use PHASE_ as the symbol to select a particular XPL build. This means
that SPL_TPL_ is no-longer set.

Update the comment in bootstage to refer to this symbol, instead of
SPL_
