ARC: remove @init_time, @init_irq platform callbacks

These are not in use for ARC platforms. Moreover DT mechanims exist to
probe them w/o explicit platform calls.

 - clocksource drivers can use CLOCKSOURCE_OF_DECLARE()
 - intc IRQCHIP_DECLARE() calls + cascading inside DT allows external
   intc to be probed automatically
