soc: renesas: Sort Renesas Kconfig configs

Renesas Kconfig is using "SoC serial 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 6d5aded ("soc: renesas: Sort driver description title")
sorted Renesas Kconfig by menu description title order, but it makes
confusable to add new config.

Let's unify "ARMxx Platform support for ${CHIP_NUMBER} (${CHIP_NAME}),
and sort it again.
