x86: EFI: Back efi_ioremap with init_memory_mapping instead of FIX_MAP
Impact: Fix boot failure on EFI system with large runtime memory range Brian Maly reported that some EFI system with large runtime memory range can not boot. Because the FIX_MAP used to map runtime memory range is smaller than run time memory range. This patch fixes this issue by re-implement efi_ioremap() with init_memory_mapping().
