pipeline: rkisp1: Match sensor aspect ratio when generating configurations

Browse source 
The RkISP1Path::generateConfiguration() function limits the maximum
resolution to the sensor resolution, to avoid upscaling. It however
doesn't take the sensor aspect ratio into account, which leads to a
maximum (and default) resolution of 1920x1920 when using the self path
with a sensor that has a higher resolution.

Fix it by constraining the minimum and maximum resolutions to match the
sensor's aspect ratio.
