Subject: [PATCH] iommu: APPLE_DART should depend on ARCH_APPLE

The Apple DART (Device Address Resolution Table) IOMMU is only present
on Apple ARM SoCs like the M1.  Hence add a dependency on ARCH_APPLE, to
prevent asking the user about this driver when configuring a kernel
without support for the Apple Silicon SoC family.
