meta-ampere: mtjade: set power policy always-on by default

Ampere BMC specification requires the chassis power policy to always-on
by default. However, it is set by default to always-off in OpenBMC.
This commit updates the setting to always-on by default.

Tested:
1. Do factory reset the BMC.
2. Check the power status
  $ root@mtjade:~# ipmitool chassis status
  Power Restore Policy : always-on
