vc/intel/fsp/wildcatlake: Expose PchHdaMicPrivacyMode

Browse source 
Expose the PchHdaMicPrivacyMode UPD parameter in the FSP-S
configuration structure for WildcatLake. This parameter controls
the HD Audio microphone privacy mode, allowing mainboards to
configure whether microphone privacy is hardware-managed,
firmware-managed, forced to mute, or disabled entirely.

TEST=Built WCL FSP successfully with this change.
