[media] davinci: ccdc_update_raw_params() frees the wrong thing

Passing a physical address to free_pages() is a bad idea.
config_params->fault_pxl.fpc_table_addr is set to virt_to_phys()
of __get_free_pages() return value; what we should pass to free_pages()
is its phys_to_virt().  ccdc_close() does that properly, but
ccdc_update_raw_params() doesn't.
