Add support for T7 power controller. T7 power control
registers are in secure domain, and should be accessed by SMC.

turn on the power.

Some power domains depends on other domains, Such as Amlogic T7 SoC.
Add parent node to support this case.

Some power domains for C3 can be using runtime PM,
remove ALWAYS_ON property. And add some power domains
description when ALWAYS_ON property.

It has been pointed out that naming a subsystem "genpd" isn't very
self-explanatory and the acronym itself that means Generic PM Domain, is
known only by a limited group of people.
In a way to improve the situation, let's rename the subsystem to pmdomain,
which ideally should indicate that this is about so called Power Domains or
"PM domains" as we often also use within the Linux Kernel terminology.
