pipeline: rkisp1: Fix config validation when dewarper is used

Browse source 
When the dewarper is used, config->validate() needs to take the
restrictions of the dewarper into account. Add the corresponding checks.

As the useDewarper_ variable is now accessed earlier in
PipelineHandlerRkISP1::configure(), ensure it gets set early enough.
