In some configurations, the dai registers get written before the bias
level is changed in the codec driver. This leads to a situation where
an initial write to the serial port register gets ignored, and future
writes may as well, since regmap thinks that the codec already holds the
value. More specifically, configuring the codec as i2s master would in
fact result in the codec running as slave, a situation where no i2s
clocks are generated and hence no data is transferred.
This change makes sure that regmap only caches writes when the core
clock is disabled, and syncs regmap whenever enabling the core clock
again.

The dapm field of the snd_soc_codec struct is eventually going to be
removed, in preparation for this replace all manual access to
codec->dapm with snd_soc_codec_get_dapm().

All drivers have the same line at the end of the set_bias_level callback to
update the bias_level state. Move this update into
snd_soc_dapm_force_bias_level() and remove them from the drivers.

To be able to read back data from the DSP parameter memory the register
range needs to be marked as readable. At the same time we do not want them
to e.g. appear in debugfs output so mark them as precious as well.

The v2 file format of the SigmaDSP takes a more declarative style compared
to the imperative style of the v1 format. In addition some features that are
supported with v2 require the driver to keep state around for the firmware.
This requires a bit of restructuring of both the firmware loader itself and
the drivers making use of the firmware loader.
Instead of loading and executing the firmware in place when the DSP is
configured the firmware is now loaded at driver probe time. This is required
since the new firmware format will in addition to the firmware data itself
contain meta information describing the firmware and its requirements and
capabilities. Those will for example be used to restrict the supported
samplerates advertised by the driver to userspace to the list of samplerates
supported for the firmware.
This only does the restructuring required by the v2 format, but does not
yet add support for the new format itself.

The codec field of the snd_soc_widget struct is eventually going to be

For the input PGA to work correctly the ALC clock needs to be active.
Otherwise volume changes are not applied.

Set the CODEC driver's suspend_bias_off flag rather than manually going to
SND_SOC_BIAS_OFF in suspend and SND_SOC_BIAS_STANDBY in resume. This makes
the code a bit shorter and cleaner.

This patch adds support for the Analog Devices ADAU1361 and ADAU1761 CODECs.
The device is a a low-power, 24-bit stereo audio CODEC with multiple analog
input and outputs, one digital microphone input and an I2S interface. The device
can be controlled either via I2C or SPI. The main difference between the two
variants is that the ADAU1761 has a built-in SigmaDSP, while the ADAU1361 has
not.
