iPS_LoadSysEncKey()
This function loads the system keys. The new values must be presented
encrypted under the current value of VSS_KLK.
Contrary to the clear text loading, this encrypted loading does not erase all other
secrets in the unit.
An error code will be returned if the VSS_KLK is not present.
