[PATCH 3/7] efi: move fdt helper library

[Leif Lindholm]

There is nothing ARM64 (or even ARM) specific about the efi fdt helper
library, which is used for locating or overriding a firmware-provided
devicetree in a UEFI system - so move it to loader/efi for reuse.

Move the fdtload.h include file to grub/efi and move the EFI page size
definitions to grub/efi/memory.h. (These definitions refer strictly to
allocation operations, as opposed to translation granules.)
