If a DAI specifies "#sound-dai-cells = <0>" in device-tree then
hdmi_of_xlate_dai_name() will be called with zero args, which it isn't
implemented to cope with. The resulting use of an uninitialised variable
for the id will usually result in an error like:

  asoc-simple-card sound: parse error -11
  asoc-simple-card: probe of sound failed with error -11

Fix this by using and id of zero if no arg is provided.

da7219 output (for headset capture) should be set to high-impedance when
not in use, since it will otherwise interfere with output from other
codecs attached to the same DAI.

Some registers accesses are done in atomic context.
Enable fast io to use spinlock instead of mutex to protect access.

rt298_jack_detect may be called before card is instantiated. And
snd_soc_dapm_force_enable_pin will not work in that case. So, update
bit manually by regmap_update_bits.

We increment "i" before printing the debug statement.  That makes it
the wrong sleep_time[] information and Smatch complains that the last
increment could be beyond the end of the array.

Mismatching stream names in DAPM route and widget definitions are
causing compilation errors. Fixing these names allows the cs4270
driver to compile and function.

The set_bias_level toggles the PDN signal when entering
SND_SOC_BIAS_STANDBY and SND_SOC_BIAS_OFF. However this has no effect and
actually breaks things down (tested with TAS5717) due to the following
reasons:

1) holding down PDN does not save power but holding down RST does
2) now hard mute via register 0x5 is implemented and therefore it is no
   longer needed to toggle PDN to enter all channel shut down
3) in order to leave PDN it is required to toggle the RST signal (see
   TAS5721 datasheet), which was not implemented
4) toggling PDN as implemented actually mutes PWMs and there is no audio
   output (tested on TAS5717)

For these reasons remove the PDN signal toggling and just initialize it to
inactive in probe().

TAS5721 datasheet recommends to wait at least 13.5ms after deasserting the
RESET signal. For TAS5717 this time is only 12ms, which was the original
value in the code.

Extend the wait time after deasserting RESET from 12 to 13.5ms to comply
with the TAS5721 specification.
