Lorenzo Stoakes c707a68f94 mm: abstract io_remap_pfn_range() based on PFN 
The only instances in which we customise this function are ones in which we
customise the PFN used.

Instances where architectures were not passing the pgprot value through
pgprot_decrypted() are ones where pgprot_decrypted() was a no-op anyway, so
we can simply always pass pgprot through this function.

Use this fact to simplify the use of io_remap_pfn_range(), by abstracting
the PFN via io_remap_pfn_range_pfn() and using this instead of providing a
general io_remap_pfn_range() function per-architecture.
