ALSA: hdac: Remove usage of struct hdac_ext_bus and use hdac_bus instead

Browse Source 
This patch removes the hdac_ext_bus 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 driver definition.
