aarch64: Make indexed_za use 64-bit immediates

Browse Source 
A later patch moves the range checking for ZA vector select
offsets from gas to libopcodes.  That in turn requires the
immediate field to be big enough to support all parsed values.

This shouldn't be a particularly size-sensitive structure,
so there should be no memory problems with doing this.
