Send TPer Reset command to reset eDrive to lock all protected bands.
Typically, there are 2 mechanism for resetting eDrive. They are:
1. TPer Reset through IEEE 1667 protocol.
2. TPer Reset through native TCG protocol.
This routine will detect what protocol the attached eDrive comform to, TCG or
IEEE 1667 protocol. Then send out TPer Reset command separately.
