Subject: [PATCH v2 08/14] media: dt-bindings: nxp,imx8mq-mipi-csi2: Add
 i.MX8QM(QXP) compatible strings

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

Add compatible strings for i.MX8QM/i.MX8QXP platform. Remove
fsl,mipi-phy-gpr from required properties and add 'phys', since i.MX8QM and
i.MX8QXP  use standard phy interface.

Keep the same restriction for other compatible strings.

change from v1 to v2
- remove internal review tags
- remove reg maxitems:1
- remove 8ulp part
- add 8qxp compatible string and make 8qm failback to 8qxp
- limit reset and power domain number to 1 for 8qxp and 8qm
- remove power-domains change because 8qm/8qxp only need 1 power domain
