Subject: iommu/dart: APPLE_DART should depend on ARCH_APPLE
Git-commit: faf8e7539643ed958174ad3dfeb43c179a9c4397
Patch-mainline: v5.15-rc1
References: bsc#1192202

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.
