[PATCH] iommu/apple-dart: correct CONFIG_PCIE_APPLE macro name in comment

[Ethan Nelson-Moore]

A comment in drivers/iommu/apple-dart.c incorrectly refers to
CONFIG_PCI_APPLE instead of CONFIG_PCIE_APPLE. Correct it.

Discovered while searching for CONFIG_* symbols referenced in code but
not defined in any Kconfig file.
