[media] davinci: vpif: Fix module build for capture and display

export the symbols which are used by two modules vpif_capture and vpif_display. renamed "ch_params" to "vpif_ch_params" so as to avoid name collision. This patch fixes following error: ERROR: "ch_params" [drivers/media/platform/davinci/vpif_display.ko] undefined! ERROR: "vpif_ch_params_count" [drivers/media/platform/davinci/vpif_display.ko] undefined! ERROR: "vpif_base" [drivers/media/platform/davinci/vpif_display.ko] undefined!
