ALSA: hda - ELD proc interface write updates
- rename ELD proc write routine to hdmi_write_eld_info()
- support modifying WMAPro's profile
Write to some ELD fields (monitor_name, manufacture_id, product_id,
eld_version, edid_version) are deliberately not supported, since that
won't correct wrong behaviors and only leads to confusions.
