Subject: [PATCH v1 3/6] arm64: dts: imx8mp-var-som: Remove UART2 console

The VAR-SOM-MX8MP does not include an onboard console connector. The
debug UART is provided on the Symphony carrier board, and customers may
choose to expose any UART controller on their own carrier designs.

Since UART2 is not populated on the SOM, drop the UART2 node from the
SOM device tree.
