ALSA: hda: Move common haswell init to a helper

Geminilake vendor nid is different from other Skylake variants, but rest
of the initialization code is same.

So a variable is added in hdmi_spec to store the platform specific vendor
nid and move the initialization code to a helper function to be used by
both platform specific init.
