libcamera: pipeline: rkisp1: fix crop configuration

Browse Source 
Crop rectangle was not being configured on the isp output pad nor in the
resizer input pad, causing an unecessary crop in the image and an
unecessary scaling by the resizer when streaming with a higher
resolution then the default 800x600.

Example:
    cam -c 1 -C -s width=3280,height=2464

In the pipeline:
    sensor->isp->resizer->dma_engine

isp output crop is set to 800x600, which limits the output format to
800x600, which is propagated to the resizer input format set to 800x600,
and the resizer output format is set to the desired end resolution
3280x2464.
