[IA64] simplified efi memory map parsing
New version leaves the original memory map unmodified. Also saves any granule trimmings for use by the uncached memory allocator. Inspired by Khalid Aziz (various traces of his patch still remain). Fixes to uncached_build_memmap() and sn2 testing by Martin Hicks. Signed-off-by: Tony Luck <tony.luck@intel.com>
