Added support for Qualcomm RPMH power domain driver, responsible
for managing power domains on Qualcomm SoCs. This is a port of
the Linux RPMHPD driver [1] and sa8775p related changes. The
power domain driver currently has support to power on and off
MMCX power domain of sa8775p; support for other soc entries power
domains are stubbed, in future, the required soc support can be
added.

Upstream DT uses simple-pm-bus instead of simple-bus. simple-pm-bus
requires power domain support. On am33xx, PRM manages power domains but
all domains are enabled at boot. Add stub driver with custom of_xlate
that expects no argumetns to allow simple-pm-bus and dependent devices
to probe.

Agilex5 FSBL is required to disable the power of unused peripheral SRAM
blocks to reduce power consumption.

Introducing a new power manager driver for Agilex5 which will be called
as part of Agilex5 SPL initialization process.

This driver will read the peripheral handoff data obtained from the
bitstream and will power off the specified peripheral's SRAM from the
handoff data values.

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 XPL_ as the symbol to indicate an SPL build. This means that SPL_ is
no-longer set.

Add trivial driver for i.MX8MP HSIOMIX handling. This is responsible
for enabling the GPCv2 power domains and clock for USB 3.0 and PCIe
in the correct order. Currently supported is the USB 3.0 part which
can be tested, PCIe support should be easy to add.
