soc/intel/alderlake: Add enum for HDA audio configuration
This change adds an enum to configure the audio related UPDs used for
configuring the audio over HDMI/DP and rename a variable for better
readability.
TEST=On shadowmountain audio sound cards are detected and listed by the
Linux kernel. Audio playback and capture is working fine.
