Add omap_gpio_disable_irq and omap_gpio_enable_irq
calls in gpio-omap.
Currently, kernel cannot disable gpio interrupts in
case of a irq storm, so add omap_gpio_disable/enable_irq
so that interrupts can be disabled/enabled.

Thanks for this patch. Can you give a bit more context on the
problem(s) this solves and on which SoCs/platforms it was
developed/validated?
Sorry for the late response. Patch was tested/developed on am335x
device BBB, If you feed a PWM signal at 200KHz frequency to
GPIO, and execute gpiomon 0 12 &, Linux will be unresponsive
even after CTRL+C without these 2 functions in this patch. Once
this patch is applied, you can get console back after hitting
CTRL+C and then proceed to kill gpiomon.
