Add to the kernels boot memory map 'memmap' entries found in the EFI memory descriptors passed in from the BIOS. On EFI systems, up to E820MAX == 128 memory map entries can be passed via the legacy E820 interface (limited by the size of the 'zeropage'). These entries can be duplicated in the EFI descriptors also passed from the BIOS, and possibly more entries passed by the EFI interface, which does not have the E820MAX limit on number of memory map entries. This code doesn't worry about the likely duplicate, overlapping or (unlikely) conflicting entries between the EFI map and the E820 map. It just dumps all the EFI entries into the memmap[] array (which already has the E820 entries) and lets the existing routine sanitize_e820_map() sort the mess out.
