iommu/vt-d: add wrapper functions for page allocations
In order to improve observability and accountability of IOMMU layer, we
must account the number of pages that are allocated by functions that
are calling directly into buddy allocator.
This is achieved by first wrapping the allocation related functions into a
separate inline functions in new file:
drivers/iommu/iommu-pages.h
Convert all page allocation calls under iommu/intel to use these new
functions.
