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

Here's v4 patch and has been landed on drm-tip,
https://patchwork.freedesktop.org/patch/msgid/20210217180016.1937401-1-lyude@redhat.com,
so revert the old and resend the v4 patch. 
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.
