New HDA controllers from Intel have extended HDA capabilities like multilink, pipe processing, SPIB, GTS etc In order to use them we create an extended HDA bus, controller and stream which uses the extended configuration
Changes in v8: - fixed some dead codec crept in - checkpatch cleanup
Changes in v7: - Feedback from Takashi - removed the macros for register read/writes - add new macros for reg update - fix bus pointer macro - header cleanup on c/h files - new device name ehdaudioiDn - removed flags for ext caps, use pointer only - moved module info to patch 1 - sparse check on series - remove codec name in link
