Subject: [PATCH v2 3/3] arm64: dts: imx8mq: add mipi csi phy and csi bridge descriptions

Describe the 2 available CSI interfaces on the i.MX8MQ with the MIPI-CSI2
receiver and the CSI Bridge that provides the user buffers, where the
existing driver can directly be used.

An image sensor is to be connected to the MIPIs' second port, described in
board files.
