src/soc/intel/alderlake: Add HDA link enable parameter

This patch adds HDA link enable parameter. The PchHDaAudioLinkHdaEnable
is required to be set for HDA link signals. The FSP uses it to enable
HDA SDI signal wake/response through HDA PCR registers. Otherwise, the
HDA link is not going to work even the HDA GPIO pins are configured
properly.

TEST=Add pch_hda_link_enable = "1" in devicetree & make & ensure the
     HDA ALC711 codec (HDA configured) is recognized on ADL-S RVP
