pmdomain: renesas: sort Renesas Kconfig configs

Renesas Kconfig is using "SoC chip number" for CONFIG symbol, but is
using "SoC chip name" for menu description. Because of it, it looks
random order when we run "make menuconfig".

commit 6d5aded8d57f ("soc: renesas: Sort driver description title")
sorted Renesas Kconfig by "menu description title order" (= SoC chip
name), but it makes confusable to add new config, because developer
usually checks CONFIG symbols (= SoC chip number).

Let's indicate both "SoC chip number" and "SoC chip name" in description
and sort it again.
