[PATCH] gpio/omap: fix debounce clock handling

GPIO debounce clock can gate the PER power domain transition
and needs to be disabled in GPIO driver suspend.

The debounce clock is not getting disabled in runtime_suspend
callback because of an un-necessary bank->mod_usage check.
In omap_gpio_suspend/resume too, there is no need to do
any operation if the gpio bank is not used.

Remove the un-necessary bank->mod_usage check from
suspend callbacks.

Thanks to Kevin Hilman for pointing out this issue.
