[PATCH] arm64: dts: ti: k3-am62: Add support for MCAN

[Aswath Govindraju]

AM62 SoC has one instance of MCAN in main domain. However, its
corresponding CAN signals are not brought out through a transceiver, on the
SK board. Therefore, add the device tree node in the main dt file and set
the status to disabled in the SK board dts file.
