[PATCH v1] riscv: iommu: Kconfig: Add RISC-V to IOMMU_DMA def_bool

[Yaxing Guo]

The IOMMU_DMA configuration option is used to enable DMA mapping
support via IOMMU for platforms that require it. Currently, it is
enabled for ARM64, X86, and S390 architectures.

This patch adds RISC-V (RISCV) to the def_bool condition, enabling
IOMMU_DMA support for RISC-V platforms that have an IOMMU and require
DMA remapping.
