Subject: [PATCH 1/6] efi: refactor grub_efi_allocate_pages
Expose a new function, grub_efi_allocate_pages_real(), making it possible
to specify allocation type and memory type as supported by the UEFI
AllocatePages boot service.
Make grub_efi_allocate_pages() a consumer of the new function,
maintaining its old functionality.
Also delete some left-around #if 1/#else blocks in the affected
functions.

Subject: [PATCH 2/6] Remove grub_efi_allocate_pages.
grub_efi_allocate_pages Essentially does 2 unrelated things:
* Allocate at fixed address.
* Allocate at any address.
To switch between 2 different functions it uses address == 0 as magic
value which is wrong as 0 is a perfectly valid fixed adress to allocate at.

Subject: [PATCH 3/6] arm64/efi: move EFI_PAGE definitions to efi/memory.h
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.

Subject: [PATCH 5/6] efi: Add grub_efi_get_ram_base() function for arm64
Since ARM platforms do not have a common memory map, add a helper
function that finds the lowest address region with the EFI_MEMORY_WB
attribute set in the UEFI memory map.
Required for the arm64 efi linux loader to restrict the initrd
location to where it will be accessible by the kernel at runtime.
