Here is the series to enable the RWDT on V3U. I took the DTS patches
from the BSP, the rest was developed on mainline tree. Note that
currently, the bootloader does not unmask the RWDT reset for us. This is
why patch #5 is needed if you want a reboot. We need to see if this is
going to be added to the bootloader later. Also, while the normal
watchdog trigger works flawlessly, the 'reboot' command will triger a
OOPS. This is a known issue also present on other Gen3 SoCs and will
be addressed seperately soon.

Other than that, patch #1 should go in via watchdog, the rest via
Geert's various trees :)

Looking forward to comments.

Happy hacking and have a nice weekend!
