ACPI/IORT: Fix CONFIG_IOMMU_API dependency

Browse source

The IOMMU probe deferral IORT rework had to add code in
iort_iommu_configure() and iort_iommu_xlate() that requires
the IOMMU_API to be selected in order to compile and work.

Stub out the pieces of code that depend on CONFIG_IOMMU_API
to be selected to prevent compilation failures such as:

drivers/acpi/arm64/iort.c: In function 'iort_iommu_xlate':
drivers/acpi/arm64/iort.c:647:22: error: 'struct iommu_fwspec' has no
member named 'ops'

by wrapping the code in static inline functions that provide a NOP
implementation when CONFIG_IOMMU_API is not selected.
