[PATCH 1/5] media: dt-bindings: nxp,imx8mq-mipi-csi2: Add i.MX8ULP compatible string

[guoniu . zhou]

From: Guoniu Zhou <guoniu.zhou@xxxxxxx>

The CSI-2 receiver in the i.MX8ULP is almost identical to the
version present in the i.MX8QXP/QM. But have different reset
and clock design, so add a device-specific compatible string
for i.MX8ULP to handle the difference.
