soc: renesas: Make RZ/Five depend on !DMA_DIRECT_REMAP

Randy reported yet another build issue with randconfigs on rv32:
WARNING: unmet direct dependencies detected for DMA_GLOBAL_POOL
  Depends on [n]: !ARCH_HAS_DMA_SET_UNCACHED [=n] && !DMA_DIRECT_REMAP [=y]
  Selected by [y]:
  - ARCH_R9A07G043 [=y] && SOC_RENESAS [=y] && RISCV [=y] && NONPORTABLE [=y] && RISCV_ALTERNATIVE [=y] && !RISCV_ISA_ZICBOM [=n] && RISCV_SBI [=y]

This happens when DMA_DIRECT_REMAP is selected by the T-Head CMO erratum
option and DMA_GLOBAL_POOL is selected by the Andes CMO erratum. Block
selecting the RZ/Five config option, and by extension DMA_GLOBAL_POOL,
if DMA_DIRECT_REMAP has already been enabled.
