Changes in V3:
- Actually I missed to remove the clocks in V2 which are supposed to
be removed. In V3 I have removed those and they are
GCC_APSS_AHB_CLK, GCC_APSS_AHB_CLK_SRC, GCC_APSS_AXI_CLK
- For the same, didn't add the Reviewed-By tags from Stephen and
Krzysztof
Changes in V2:
- property 'clocks' is marked required
- Renamed the include file name to match with compatible
