[media] vpif: Consolidate formats from capture and display

Browse Source 
- The ch_params tables in vpif_capture.c and vpif_display.c are moved to a common
  table in vpif.c. Then it is easier to maintain the table.
- The field "fps" is removed from the struct vpif_channel_config_params because it
  is not used.
