Support YUV420P in the i.MX6 video node

Camera input is often in this format. Until now the lack of GL_VIV_I420 (which
was presumably missing in older versions of the extension?) in the format list
resulted in falling back to the built-in i420 node instead of the zero-copy imx6
one. This is now corrected by adding the correct format mapping.
