iommu: Make IPMMU_VMSA dependencies more strict

On riscv64, linux-next-20233030 (and for several days earlier),
there is a kconfig warning:

WARNING: unmet direct dependencies detected for IOMMU_IO_PGTABLE_LPAE
  Depends on [n]: IOMMU_SUPPORT [=y] && (ARM || ARM64 || COMPILE_TEST [=n]) && !GENERIC_ATOMIC64 [=n]
  Selected by [y]:
  - IPMMU_VMSA [=y] && IOMMU_SUPPORT [=y] && (ARCH_RENESAS [=y] || COMPILE_TEST [=n]) && !GENERIC_ATOMIC64 [=n]

and build errors:

io-pgtable-arm.c:(.init.text+0x1e8): undefined reference to `alloc_io_pgtable_ops'

Add ARM || ARM64 || COMPILE_TEST dependencies to IPMMU_VMSA to prevent
these issues, i.e., so that ARCH_RENESAS on RISC-V is not allowed.

This makes the ARCH dependencies become:
	depends on (ARCH_RENESAS && (ARM || ARM64)) || COMPILE_TEST
but that can be a bit hard to read.
