efi_loader: allow compiling with clang

On ARM systems gd is stored in register r9 or x18. When compiling with
clang gd is defined as a macro calling function gd_ptr(). So we can not
make assignments to gd.

In the UEFI sub-system we need to save gd when leaving to UEFI binaries and
have to restore gd when reentering U-Boot.

Define a new function set_gd() for setting gd and use it in the UEFI
sub-system.
