Jan Kiszka 82750ce442 arm: dts: iot2050: Fix by syncing from Linux
This restores support for IOT2050 by widely synchronizing its DT files
with the Linux kernel. We additionally need to add the alias restoration
that is still waiting for its upstream merge and the not-yet-upstreamed
bits needed for watchdog reboot detection.

Fixes: 4dbdc84754 ("arm: dts: k3-am654: pull in dtb update from Linux")
