Subject: [PATCH v1 1/2] arm64: dts: imx8mq: fix mipi_csi bidirectional port numbers

The port numbers for the imx8mq mipi csi controller are wrong and
the mipi driver can't find any media devices as port@1 is connected
to the CSI bridge, not port@0. And port@0 is connected to the
source - the sensor. Fix this.

Fixes: bcadd5f66c2a ("arm64: dts: imx8mq: add mipi csi phy and csi bridge descriptions")
