efi_loader: move efi_save_gd() call to board_r.c

Browse source 
The first functions of the UEFI sub-system are invoked before reaching the
U-Boot shell, e.g. efi_set_bootdev(), efi_dp_from_name(),
efi_dp_from_file(). We should be able to print out device paths for
debugging purposes here.

When printing device paths via printf("%pD\n", dp) this invokes functions
defined as EFIAPI. So efi_save_gd() must be called beforehand.

So let's move the efi_save_gd() call to function initr_reloc_global_data(()
in board_r.c.
