ALSA: hda/tas2781: Add tas2781 HDA driver

Browse Source 
Create tas2781 side codec HDA driver for Lenovo Laptops. The quantity
of the speakers has been define in ACPI. All of the tas2781s in the
laptop will be aggregated as one audio speaker. The code supports
realtek codec as the primary codec. Code offers several controls for
digtial/analog gain setting during playback, and other for eq params
setting in case of different audio profiles, such as music, voice,
movie, etc.
