Ah, I found a mcu_uart0 pinmuxing in ti-u-boot's k3-am654-r5-base-
board.dts. So I assume that the muxing is installed by the bootloader,
and the kernel expects that this muxing is already in place, so that
mcu_uart0 can work? Is there a reason not to make the pinmuxing
explicit by copying it to the kernel's k3-am654-base-board.dts?
