ALSA: hda - hdmi: Fix IEC958 ctl indexes for some simple HDMI devices
In case a single HDA card has both HDMI and S/PDIF outputs, the S/PDIF outputs will have their IEC958 controls created starting from index 16 and the HDMI controls will be created starting from index 0. However, HDMI simple_playback_build_controls() as used by old VIA and NVIDIA codecs incorrectly requests the IEC958 controls to be created with an S/PDIF type instead of HDMI. In case the card has other codecs that have HDMI outputs, the controls will be created with wrong index=16, causing them to e.g. be unreachable by the ALSA "hdmi" alias. Fix that by making simple_playback_build_controls() request controls with HDMI indexes. Not many cards have an affected configuration, but e.g. ASUS M3N78-VM contains an integrated NVIDIA HDA "card" with: - a VIA codec that has, among others, an S/PDIF pin incorrectly labelled as an HDMI pin, and - an NVIDIA MCP7x HDMI codec.
