ipa: rkisp1: Use IPAConfig in IPA::configure()

The RkISP1 implementation of IPA::configure() still uses the legacy
interface where sensor controls (and eventually lens controls) are
passed from the pipeline handler to the IPA in a map.

Since the introduction of mojom-based IPA interface definition, it is
possible to define custom data types and use them in the interface
definition between the pipeline handler and the IPA.

Align the RkISP1 IPA::configure() implementation with the one in the
IPU3 IPA module by using a custom data type instead of relying on a map
to pass controls to the IPA.
