mb/system76/adl: Remove duplicate PchHdaAudioLinkHdaEnable

This UPD is hooked up in devicetree since commit 854bd492fcfa
("mb/{system76,msi}: Enable PchHdaAudioLinkHdaEnable via devicetree").

As these boards were in development when the change happened, they still
had the UPD set via romstage. Remove them now so they are only set in
devicetree.
