riscv: Kconfig: Select DMA_DIRECT_REMAP only if MMU is enabled
kernel/dma/mapping.c has its use of pgprot_dmacoherent() inside
an #ifdef CONFIG_MMU block. kernel/dma/pool.c has its use of
pgprot_dmacoherent() inside an #ifdef CONFIG_DMA_DIRECT_REMAP block.
So select DMA_DIRECT_REMAP only if MMU is enabled for RISCV_DMA_NONCOHERENT
config.
This avoids users to explicitly select MMU.
