pipeline: raspberrypi: Split out device enumeration and camera registration

Browse source 
Split out PipelineHandlerRPi::match() so that media device enumeration and
acquisition is separated from camera registration. The former logic remains
in PipelineHandlerRPi::match(), whereas the latter logic is moved into a new
PipelineHandlerRPi::registerCamera() member function.
