pmdomain: renesas: rmobile-sysc: fix -Wvoid-pointer-to-enum-cast warning
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*.
