ipa: rkisp1: Use the new ISP parameters abstraction

Use the new ISP parameters abstraction class RkISP1Params to access the
ISP parameters in the IPA algorithms. The class replaces the pointer to
the rkisp1_params_cfg structure passed to the algorithms' prepare()
function, and is used to access individual parameters blocks.
