ALSA: hda: hdmi - fix regression in connect list handling
Fix regression in how intel_haswell_fixup_connect_list() results are used in hda_read_pin_conn(). Use of snd_hda_get_raw_connections() in hda_read_pin_conn() bypasses the cache and thus also bypasses the overridden pin connection list. On platforms that require the connection list fixup, mux list will be empty and HDMI playback will fail to -EBUSY at open. Fix the regression in hda_read_pinn_conn(). Simplify code as suggested by Takashi Iwai to remove old intel_haswell_fixup_connect_list() and copy the cvt_nid list directly and not use snd_hda_override_conn_list() at all.
