host-restart: set restart reason on scheduling use

When the scheduling feature is the reason for a power on of the system,
set the RestartCause property appropriately.

This property is used by other software on some systems to guide
partition behaviors in the host code.

Tested:
- Utilize the scheduling feature to start a boot of the system and
  verified the RestartCause was set to ScheduledPowerOn
