[Impact]
On CML-R, after S3, No screen show on all three connector(3*DP).

[Fix]
For Legacy S3 suspend/resume GEN9 BC needs to enable and setup TGP PCH.

[Test Case]
1. Connected the monitor on one of 3*DP on CML-R.
2. Suspend&resume the machine.
3. Check the monitor can output something.

[Where problems could occur]
Just Enable the hpd detection in IRQ installer and during suspend&resume.
