[PATCH v2 1/2] arm64: dts: ti: k3-am62: Add MCU MCAN nodes

[Francesco Dolcini <francesco@dolcini.it>]

From: Judith Mendez <jm@ti.com>

On AM62x 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] 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")

     fixed reg/reg-names order]
