clockevents/drivers/mips-gic: Migrate to new 'set-state' interface
Migrate mips-gic driver to the new 'set-state' interface provided by
clockevents core, the earlier 'set-mode' interface is marked obsolete
now.
This also enables us to implement callbacks for new states of clockevent
devices, for example: ONESHOT_STOPPED.
We weren't doing anything in the ->set_mode() callback. So, this patch
doesn't provide any set-state callbacks.
