Create a list of handlers for each ISP block that wraps the existing configuration functions and handles the ISP block enablement state. Parse the configuration parameters buffer in __rkisp1_ext_params_config and filter the enable blocks by group, to allow setting the 'other' and 'meas' groups separately from the 'lsc' group to support the pre/post-configure operations.
