When setting the sink format of the 'rkisp1_resizer'
the format should be supported by 'rkisp1_isp' on
the video source pad. This patch checks this condition
and set the format to default if the condition is false.

I think we can rename this macro to state explicitly it is the direction from the rkisp1_isp subdevice node
point of view.
Maybe prefix it with RKISP1_ISP_SD_ ?
yes, it's a better name.
Thanks

I also think the field 'direction' better change to isp_pads_flags.
It indicates better what this field is.
Thanks,
