mb/intel/adlrvp: Use HDA TMODE 8T to match spec for ADL P RVP
With current setting Display audio codec probe fails.
Hence HDMI/DP audio fails.
Earlier, with FSP 2037 was used the mode was incorrectly programmed to 4T
This setting was carried ahead with below change:
Commit : 50f8b4ebdd7db8077b87ab7686637599c9d93af3
The issue was fixed in later FSPs and with current
FSP v2237, we need to set the TMODE to 8T as per spec.
TEST=Verify HDMI/DP Playback on ADL P RVP
Fixes: 50f8b4ebdd7db8077b87ab7686637599c9d93af3
