Add support for DPSPARSER object (create/destroy, open/close, apply spb) which is required to configure Soft Parser by using MC. Also add uboot command to apply Soft Parser Blob with command: fsl_mc apply spb <spb_load_addr> Signed-off-by: Florinel Iordache <florinel.iordache@nxp.com> Signed-off-by: Priyanka Jain <priyanka.jain@nxp.com>
