Add 'clock-names' to the gpio dt node. so the driver could get clocks by a const char id, this patch names the clock-names as - 'bus': the apb clock for cpu to access the gpio controller - 'db': the debounce clock for cpu to set debounce clock rate Since the old dt nodes may have no clock-names, this patch not make them as part of 'required properties'.
