reg-config: ensure runs before chassis power on

openbmc/phosphor-state-manager#16 documents an issue with the
[email protected]. Root cause is unknown at this point. Until
root cause is understood there, set the service dependency directly to
ensure this service always runs prior to chassis power being turned on.

Tested:
- Ran 10 power on/off and verified this service always ran before power
  was turned on to the chassis.
