wrong value reported for DPM Input HandshakeMode, DPM Output HandshakeMode and DPM Sync HandshakeMode

Currently, the firmware reports all three HandshakeModes with value 0.

Expected behavior is to report

• "HIL_IO_MODE_BUFF_HST_CTRL" for Input HandshakeMode and Output HandshakeMode
• "HIL_SYNC_MODE_HST_CTRL" for Sync HandshakeMode

This is a cosmetic modification which does not modify the actual implementation of Handshake or system behavior. It only reflects that the very first toggle of a Handshake will be initiated by host.
