Set the ->irq_enable() and ->irq_disable() methods to NULL
to enable lazy disable of interrupts. This by itself provides
some level of optimization, but is mainly enabled as ground
work for future Suspend-to-RAM wake up support.

(cherry picked from commit 664734c012e6f3a88b2da4c586002cd62a277003)
(Queued by Linus Walleij for v3.14 but not yet in Linus's tree)
