When system registers are not enabled, all the access to them will trap

in EL2. In Xen, system registers will be enabled by gicv3_cpu_init only
on success. As the rest of the code (e.g gicv3_hyp_init) relies on
system register, it is better to bail out directly.
This will save time on debugging early boot issue on GICv3 platform.

This is good:

Do we also want to print a warning or an error message?
AFAICT, all the path that return an error in gicv3_cpu_init (and the
callers) have already a warning/error message. So no need to add an
extra one here.
