Commit adc421e4cee8 "arm: move gd handling outside of C code" removed the call to arch_setup_gd() on ARM and replaced it with assembly code in crt0.S. However, AArch64 uses a different startup file, and the same change was not made to it. This leaves gd uninitialized on AArch64, which typically leads to hangs or crashes. This change fixes that.
