mmc: host: Kconfig: Make MMC_SDHI_INTERNAL_DMAC config option dependant on ARCH_RENESAS

MMC_SDHI_INTERNAL_DMAC config option has dependency on ARM64 and
R7S9210/R8A77470 this dependency will keep growing for future SoCs for
varying architectures. So to simplify this configuration make
MMC_SDHI_INTERNAL_DMAC solely depend on ARCH_RENESAS, as all Renesas
SoCs inherently depend on the ARCH_RENESAS config option.

This allows selecting MMC_SDHI_INTERNAL_DMAC config option for RZ/Five SoC
which is based on RISC-V architecture.
