Revert "systemd: enable watchdog and set watchdog device to wdt2"

This reverts commit 9aeb8f0961e8d431192321c188af62b7e1831ad5.

Systemd is failing to ping the watchdog while shutting down, resulting
in a BMC reset during the shutdown. This results in an unclean shutdown
and side switching to the alternate BMC chip.

Resolves openbmc/openbmc#3094
