[PATCH 1/2] dt-bindings: gpio: rockchip: add clock-names

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'.
