ARM: dts: Coibri iMX6ULL: use wdog HW signal for reset
The i.MX6 ULL's watchdog is used to reset the SoC on reboot. The watchdog is
configured to use the SoC's internal reset signal which does not generate a
reset pulse on nRESET_OUT. Change the watchdog configuration to use a SoC
external HW signal.
This will additionally change the 'Reset cause' message from U-Boot
from WDOG to POR.
