meta-ampere: mtjade: disable the poweron watchdog

Ampere Mt.Jade power control involves different action during the
course of action which does not involve rebooting the Host.  Thus
disable the use of Host Power-On watchdog.

Tested:
    1. Power on host.
    2. In bmc console call "journalctl -f".
    3. "ipmitool power reset" make sure there are no
       phosphor-watchdog messages.
