[PATCH/RFC 01/03] irqchip: renesas-irqc: Add irq_enable() and irq_disable()

[Magnus Damm <magnus.damm@gmail.com>]

From: Magnus Damm <damm+renesas@opensource.se>

Hook up ->irq_enable() and ->irq_disable() together with
->irq_mask() and ->irq_unmask(). This should not adjust
any code behaviour at all.
