ALSA: hda - Add api_version to hda_device_id struct
For distinguishing the difference between HDA legacy and ext codec driver entries, we need to expose the value corresponding to type field. This patch adds a new field, api_version, to hda_device_id struct, so that this information is embedded in modalias string. Although the information is basically redundant (struct hdac_device already has type field), the helper that extracts from MODULE_DEVICE_TABLE() won't take it account except for the exported table entries themselves. So we need to put the same information in the table, too.
