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.
