[PATCH v2] drivers/vfio: Allow type-1 IOMMU instantiation with all ARM/ARM64 IOMMUs

[Geert Uytterhoeven <geert+renesas-gXvu3+zWzMSzQB+pC5nmwQ@public.gmane.org>]

Currently the type-1 IOMMU instantiation depends on "ARM_SMMU ||
ARM_SMMU_V3", while it applies to other ARM/ARM64 platforms with an
IOMMU (e.g. Renesas VMSA-compatible IPMMUs).

Instead of extending the list of IOMMU types on ARM platforms, replace
the list by "ARM || ARM64", like other architectures do.  The feature is
still restricted to ARM/ARM64 platforms with an IOMMU by the dependency
on IOMMU_API.

Tested with sata_rcar on Renesas R-Car H3 ES2.0.

This causes a trivial merge conflict with commit c01eaa95ad30897b ("Make
anon_inodes unconditional") in vfs/for-next.

v2:
  - Make the feature just depend on ARM || ARM64, instead of adding yet
    another IPMMU_VMSA dependency, as suggested by Robin Murphy
    <robin.murphy-5wv7dgnIgG8@public.gmane.org>.
