x86 and ia64 implement efi_mem_attributes() differently. This function needs to be available for other arch (such as arm64) as well, such as for the purpose of ACPI/APEI.
ia64 efi does not setup memmap variable and does not set EFI_MEMMAP flag, so it needs to have its unique implementation of efi_mem_attributes().
Move efi_mem_attributes() implementation from x86 to efi, and declare it with __weak. It is recommended that other archs should not override the default implementation.
