[media] vpif: Fix compilation with allmodconfig

When vpif is compiled as module, those errors happen:

ERROR: "vpif_lock" [drivers/media/platform/davinci/vpif_display.ko] undefined!
ERROR: "vpif_lock" [drivers/media/platform/davinci/vpif_capture.ko] undefined!

That's because vpif_lock symbol is not exported.
