libcamera: rkisp1: Generate config using main path
The generateConfiguration() implementation in the Rockchip RkISP1
pipeline handler uses by default the self path (if available) for
the Viewfinder and VideoRecording StreamRoles.
The validate() implementation, at the contrary, prefers using the main
path, when available, for all streams.
As the self-path is limited in output resolution to 1920x1920,
generating a configuration using the self path limits the maximum
stream size to 1920x1920, while higher resolutions can be obtained by
using the main path.
Align the generateConfiguration() implementation to the validate() one
by using the main path by default if available.
