[PATCH 1/1] arm: omap: gpio: define .disable callback for gpio irq chip

[Eduardo Valentin]

Currently, if one calls disable_irq(gpio_irq), the irq
won't get disabled.

This is happening because the omap gpio code defines only
a .mask callback. And the default_disable function is just
a stub. The result is that, when someone calls disable_irq
for an irq in a gpio line, it will be kept enabled.

This patch solves this issue by setting the .disable
callback to point to the same .mask callback.
