Create a list of handlers for each ISP block that wraps the existing configuration functions and handles the ISP block enablement. Parse the configuration parameters buffer in rkisp1_ext_params_config and filter the enable blocks by group, to allow setting the 'other' groups separately from the 'lsc' group to support the pre/post-configure operations. Implement the vb2 buf_out_validate() operation to validate the extensible format buffer content at qbuf time.
