ipa: rkisp1: Pass IPASettings at init call

When the IPA is initialized, it will need to know the sensor model
used in order to properly call CameraSensorHelper for the analogue gain.
Modify the init definition in the pipeline handler and in the IPA as
well as the mojo interface to pass the IPASettings.
