[PATCH] ARM: OMAP3+: fix oops triggered in omap_prcm_register_chain_handler(v1)

This patch fixes the oops below[1].

Obviously, the count of "struct irq_chip_generic" instances to be
allocated and setup should be irq_setup->nr_regs instead of
irq_setup->nr_regs plus one, so just fix the iterator to avoid
the oops.
