The RK3576 SoC needs to ungate the power domains before their status can
be modified.
The values have been taken from the rockchip downstream driver.

Some rockchip SoC need to ungate power domains before their power status
can be changed.
Each power domain has a gate mask that is set to 1 to ungate it when
manipulating power status, then set back to 0 to gate it again.

Drop OF node reference immediately after using it in
syscon_node_to_regmap(), which is both simpler and typical/expected
code pattern.

Use scoped for_each_available_child_of_node_scoped() and
for_each_child_of_node_scoped() when iterating over
device nodes to make code a bit simpler.

Use preferred device_get_match_data() instead of of_match_device() to
get the driver match data. With this, adjust the includes to explicitly
include the correct headers.

The Kconfig option belongs closer to the corresponding implementation,
hence let's move it from the soc subsystem to the pmdomain subsystem.

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.
