On AM62x SoC, MCANs on MCU domain do not have hardware interrupt
routed to A53 Linux, instead they will use software interrupt by
timer polling.

To enable timer polling method, interrupts should be
optional so remove interrupts property from required section and
add an example for MCAN node with timer polling enabled.
