Implement support in rkisp1-params for the extensible configuration
parameters format.
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.
