When building with clang 18 I see the following warning:
| drivers/soc/renesas/rmobile-sysc.c:193:22: warning: cast to smaller integer
| type 'enum pd_types' from 'const void *' [-Wvoid-pointer-to-enum-cast]
| 193 | add_special_pd(np, (enum pd_types)id->data);
This is due to the fact that `id->data` is a void* and `enum pd_types`
has the size of an integer. This cast from pointer-width to int-width
causes truncation and possible data loss. Instead, cast to `uintptr_t`
which has the same width as void*.

The Kconfig options belongs closer to the corresponding implementations,
hence let's move them 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.
