Add a Mic Jack widget to the Tegra+RT5640 machine driver, and document
this in the DT binding. This enables the DT to include the Mic Jack in
the audio routing table, and hence enables capture of audio, in addition
to the previously-working playback.

None of the delayed work the driver schedules has particularly short delays
and it is not performance sensitive so let the scheduler run it wherever
is most efficient rather than in a per CPU workqueue by using the system
power efficient workqueue.

CODECs without any outputs now remain powered down, which means any
paths to these codecs also remain powered down.
Add an always-enabled output pin widget to the spdif transceiver codec.
This enables DAPM to correctly identify that the spdif transceiver is
in use when playback is enabled, which will then allow DAPM to power up
any links from the CPU DAI to the S/PDIF transceiver.

Generally, S/PDIF supports 20bit and optional 24bit samples. Thus add these
two formats for the dummy codec drivers.
If one S/PDIF controller has its own limitation, its CPU DAI driver should
set the supported format by its own circumstance, since the soc-pcm driver
will use the intersection of cpu_dai's formats and codec_dai's formats.

Powering down PLL before switching to a mode that does not use it
is a bad idea. It would cause the SGTL5000 be without internal
clock supply, especially on the I2C interface, which would make
subsequent access to it fail.
Thus, in case of not using PLL any longer, first set the mode
control, then power down PLL.

Current rsnd driver is using struct rsnd_dai_platform_info
so that indicate sound DAI information (playback/capture SSI ID).
But, SSI settings were also required separately.
Thus, platform settings was very un-understandable.
This patch adds dai_id to SSI
settings, and removed rsnd_dai_platform_info.

In case of error, the function devm_ioremap_resource() returns ERR_PTR()
and never returns NULL. The NULL test in the return value check should be
replaced with IS_ERR(), and also remove the dev_err call to avoid redundant
error message.
