[U-Boot] [PATCH v3 8/8] efi_loader: Capture efi_add_memory_map() result efi_add_runtime_mmio()

[Bryan O'Donoghue]

efi_add_runtime_mmio() does an efi_add_memory_map() call. We have recently
changed the return value of efi_add_memory_map() to return an efi_status_t
code.

This patch captures the result code of efi_add_memory_map() and if that
result code is not EFI_SUCCESS returns EFI_OUT_OF_RESOURCES;
