This is OK for now, but I think we need to add #defines for this
sometime soon as this magic mask is not immediately obvious.

#define EFI_MEMORY_UC 0x00000001
#define EFI_MEMORY_WC 0x00000002
#define EFI_MEMORY_WT 0x00000004
...
etc
...
#define EFI_MEMORY_SP 0x00040000

#define EFI_MEMORY_ALL (EFI_MEMORY_UC | EFI_MEMORY_WC | ... | EFI_MEMORY_SP)

and then

	if (nfit_struct->memory_mapping & ~EFI_MEMORY_ALL) {
		...
