[U-Boot] [PATCH v4 08/21] efi_loader: efi_allocate_pages is too restrictive

[Alexander Graf <agraf@suse.de>]

From: Heinrich Schuchardt <xypron.glpk@gmx.de>

When running on the sandbox the stack is not necessarily at a higher memory
address than the highest free memory.

There is no reason why the checking of the highest memory address should be
more restrictive for EFI_ALLOCATE_ANY_PAGES than for
EFI_ALLOCATE_MAX_ADDRESS.

[agraf: use -1ULL instead]
