soc: renesas: Fix missing dependency on new CONFIG_CACHEMAINT_FOR_DMA

The Kconfig menu entry was converted to a menuconfig to allow it to be
hidden for !CONFIG_RISCV. The drivers under this new option were selected
by some other Kconfig symbols and so an extra select CACHEMAINT_FOR_DMA is
needed.

Fixes: 4d1608d0ab33 ("cache: Make top level Kconfig menu a boolean dependent on RISCV")
