soc/intel/tigerlake: Update iDisp Link UPD settings
Remove explicit setting of iDisp Link parameters. These settings are
related to configuration for the link between HD-Audio controller and
Display unit for purposes of HDMI/DP Audio playback. During PO,
observed that without setting these params display part was not
binding. With the latest code verified that we dont need to explicitly
set these parameters anymore. HDMI/DP audio playback works fine with
default settings.
BUG=b:151451125
BRANCH:none
TEST= build and boot volteer/ripto and verify HDMI/DP audio playback
