The verifiers framework changed the API of grub_file_open(), but did not
fix up all users. Add the file type GRUB_FILE_TYPE_DEVICE_TREE_IMAGE
to the "devicetree" command handler call.

When booting an arm* system on UEFI with an empty device tree (currently
only when hardware description comes from ACPI), we don't currently set
default to 1 cell (32 bits).
Set both of these properties, to 2 cells (64 bits), to resolve issues
with kexec on some platforms.
This change corresponds with linux kernel commit ae8a442dfdc4
("efi/libstub/arm*: Set default address and size cells values for an empty dtb")
and ensures booting through grub does not behave differently from booting
the stub loader directly.

The EFI page definitions and macros are generic and should not be confined
to arm64 headers - so move to efi/memory.h.
Also add EFI_PAGE_SIZE macro.
Update loader sources to reflect new header location.

In preparation for turning this into a common loader for 32-bit and 64-bit
platforms, ensure the code will compile cleanly for either.

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 update path to
efi/fdtload.h in source code referring to it.
