arm: initialize gd for AArch64

Browse Source 
Commit adc421e4ce "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.
