[PATCH] arm64: dts: ti: k3-am62a7: Add MCU MCAN nodes

[Judith Mendez]

On AM62ax there are no hardware interrupts routed to A53 GIC
interrupt controller for MCU MCAN IPs, so MCU MCAN nodes were
omitted from MCU dtsi.

Timer polling was introduced in commits [1][2] enabling 3x MCAN
on AM62ax, so now add MCU MCAN nodes to the mcu dtsi for the Cortex A53.

[1] commit b382380c0d2d ("can: m_can: Add hrtimer to generate software interrupt")
[2] commit bb410c03b999 ("dt-bindings: net: can: Remove interrupt properties for MCAN")
