Now that the users of gic_arch_extn have been fixed, drop the
feature for good. This leads to the removal of some now useless
locking.

doesn't really require the users of that feature to be converted
to stacked domains.
Add a gic_set_irqchip_flags() function that platform code can
call instead of using the
