[PATCH v4 01/21] rockchip/vpu: Use pixel format helpers

[Boris Brezillon <boris.brezillon-ZGY8ohtN/8qB+jHODAdFcQ@public.gmane.org>]

From: Ezequiel Garcia <ezequiel-ZGY8ohtN/8qB+jHODAdFcQ@public.gmane.org>

Now that we've introduced the pixel format helpers, use them
in vpu driver, and get rid of the internal helpers.
