gem5: Fix initialization of gem5 GIC extensions

The gem5 GIC extensions weren't initialized correctly after the 4.4
rebase. This was caused by the distributor being initialized before
the extensions were probed and enabled. This changeset moves the
initialization from the OF-specific initialization code (gic_of_init)
to the common path (__gic_init_bases).
