gpio/omap: fix incorrect access of debounce module
Enable debounce clock before writing/reading debounce registers. Disable the clock at the end so that it is synchronized with the pm_runtime_get/put_sync calls. Enable debounce clock per module. This call is mandatory because in omap_gpio_request() when *_runtime_get_sync() is called, _gpio_dbck_enable() within runtime callbck fails to turn on dbck because dbck_enable_mask used within _gpio_dbck_enable() is still not initialized at that point. Therefore we have to enable dbck here.
