e1000e: Handshake with CSME starts from ADL platforms

Handshake with CSME/AMT on none provisioned platforms during S0ix flow
is not supported on TGL platform and can cause to HW unit hang. Update
the handshake with CSME flow to start from the ADL platform.

Fixes: 3e55d23 ("e1000e: Add handshake with the CSME to support S0ix")
