[PATCH v3 17/20] ASoC: dt-bindings: tas2770: add flags for SDOUT pulldown and zero-fill

[James Calligeros]

TAS2770 can pull down and zero-fill SDOUT when not actively transmitting
TDM slot data. Zero-fill is useful when there are no other amps on the
bus. Pulldown is useful when the chip is attached to a shared bus.
