Ard Biesheuvel 61139eb040 arm64/efi: invert UEFI memory region reservation logic 
Instead of reserving the memory regions based on which types we know
need to be reserved, consider only regions of the following types as
free for general use by the OS:

EFI_LOADER_CODE
EFI_LOADER_DATA
EFI_BOOT_SERVICES_CODE
EFI_BOOT_SERVICES_DATA
EFI_CONVENTIONAL_MEMORY

Note that this also fixes a problem with the original code, which would
misidentify a EFI_RUNTIME_SERVICES_DATA region as not reserved if it
does not have the EFI_MEMORY_RUNTIME attribute set. However, it is
perfectly legal for the firmware not to request a virtual mapping for
EFI_RUNTIME_SERVICES_DATA regions that contain configuration tables, in
which case the EFI_MEMORY_RUNTIME attribute would not be set.
