[PATCH v4 RESEND 3/7] gpio/omap: fix _set_gpio_irqenable implementation

[Tarun Kanti DebBarma]

This function should be capable of both enabling and disabling interrupts
based upon the *enable* parameter. Right now the function only enables
the interrupt and *enable* is not used at all. So add the interrupt
disable capability also using the parameter.
