x86/xen: do not use _PAGE_IOMAP PTE flag for I/O mappings
Since mfn_to_pfn() returns the correct PFN for identity mappings (as used for MMIO regions), the use of _PAGE_IOMAP is not required in pte_mfn_to_pfn(). Do not set the _PAGE_IOMAP flag in pte_pfn_to_mfn() and do not use it in pte_mfn_to_pfn(). This will allow _PAGE_IOMAP to be removed, making it available for future use.
