Subject: [PATCH 08/14] media: dt-bindings: nxp,imx8mq-mipi-csi2: Add
 i.MX8QM compatible strings

From: Robert Chiras <robert.chiras@....com>

Add compatible strings for i.MX8QM platform. Remove fsl,mipi-phy-gpr from
required properties and add 'phys', since i.MX8QM use standard phy
interface.

Keep the same restriction for other compatible strings.
