[PATCH v3 2/8] sh, irq: Remove irq_reserve_irq calling

[PATCH v3 2/8] sh, irq: Remove irq_reserve_irq calling

[Yinghai Lu]

in sh calling path:
	register_intc_controller
		=> irq_create_identity_mapping/irq_create_strict_mappins
			=>irq_alloc_desc: it will set bits on allocate_irq
		=> intc_register_irq
			=> irq_reserve_irq: set bits again

so we can kill this irq_reserve_irq calling.

-v2: Fix comment style according to Sergei Shtylyov.
