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.

Dropped the Fixes tag, as this doesn't fix any real issue. Otherwise
applied with adjusted subject (iommu: -> iommu/dart:), Thanks.
