omap: GPIO: fix auto-disable of debounce clock 

The addition of the new debounce code (commit
168ef3d9a5) broke the auto-disable of
debounce clocks on idle by forgetting to update the debounce clock
enable mask.

Add back the updating of bank->dbck_enable_mask so debounce clocks are
auto-disabled.
