x86/mm, resource: Use PAGE_KERNEL protection for ioremap of memory pages
In order for memory pages to be properly mapped when SEV is active, it's
necessary to use the PAGE_KERNEL protection attribute as the base
protection. This ensures that memory mapping of, e.g. ACPI tables,
receives the proper mapping attributes.
