An extensive usage of the TAS571x driver with the TAS5717 chip revealed several
issues which in the first place caused audio to fail to play. This set of
one-line and trivial patches fixes them. 

The issues were:
* improper handling of the power-down signal
* some timings not obeyed
* bias level not saved in the driver
* channel mixer volume controls in the wrong chip structure ;-)

Petr Kulhavy (5):
  ASoC: tas571x: fix missing bias save level
  ASoC: tas571x: extend the t_i2c time to comply with TAS5721
  ASoC: tas571x: remove improper PDN signal usage in set_bias_level
  ASoC: tas571x: wait 50ms after oscillator trim
  ASoC: tas571x: move mixer volume controls from TAS5711 to TAS5717
