ALSA: hdac: Remove usage of struct hdac_ext_device and use hdac_device instead

This patch removes the hdac_ext_device structure. The legacy and
enhanced HDaudio capabilities can be handled in a backward-compatible
way without separate definitions.

Follow-up patches in this series handle the bus and driver definitions.
