Subject: [PATCH] staging: media: imx: Split config option in 2

As described in NXPs' linux tree, the imx8m SoC includes the same
CSI bridge hardware that is part of imx7d. We should be able to
use the "fsl,imx7-csi" driver for imx8m directly.

Since ipuv3 is not relevant for imx8m we create VIDEO_IMX7_MEDIA and
split up the configuration option in 2 menus (on 1 entry each
for now but that can be changed later).

Signed-off-by: Martin Kepplinger <martin.kepplinger@...i.sm>
