[PATCH v9 23/31] gpio/omap: enable irq at the end of all configuration in restore

[Tarun Kanti DebBarma]

From: Nishanth Menon <nm at ti.com>

Setup the interrupt enable registers only after we have configured the
required edge and required configurations, not before, to prevent
spurious events as part of restore routine.
