Preset EQ enum of sta32x codec driver declares too many number of
items and it may lead to the access over the actual array size.
Use SOC_ENUM_SINGLE_DECL() helper and it's automatically fixed.

This patch adds support for the ADAU1977, ADAU1978 and ADAU1979 audio CODEC
devices. They are a family of 4-channel differential input audio ADC devices.
They can be connected to either a SPI or I2C bus. The driver is implemented in
three modules, one main module (adau1977.ko) which implements the device logic
and one module each for SPI (adau1977-spi.ko) and I2C (adau1977-i2c.ko) bus
access.

There are a few known (minor) problems with having the support code for both I2C
and SPI in the same module:
* We need to be extra careful to make sure to not build the driver into the
kernel if one of the subsystems is build as a module (Currently only I2C
can be build as a module).
* The module init path error handling is rather ugly. E.g. what should be
done if either the SPI or the I2C driver fails to register. Most drivers
that implement SPI and I2C in the same module currently fallback to
undefined behavior in that case. Splitting the the driver into two
modules, one for each bus, allows the registration of the other bus drive
to continue without problems if one of them fails.
This patch splits the ADAV80X driver into 3 modules. One core module that
implements the device logic, but is independent of the bus method used. And one
module for SPI and I2C each that registers the drivers and sets up the regmap
struct for the bus.

Use devm_kzalloc() to allocate the device state struct. Saves use from having to
free it manually on the error path and in the remove callback.
Now that the adav80x_bus_probe() function is only a call to
snd_soc_unregister_codec() also inline that.

As part of phasing out the ASoC level register I/O code (which is now just
a thin wrapper around regmap anyway) convert the cs42l51 driver to use the
regmap API directly.
We now no longer initialise the cache from hardware at startup, the regmap
caches are smart enough to understand which registers are actually cached
and read on demand. This should have no visible effect on the system.

Currently the I2C device Ids conflict for the MFD and CODEC so
cannot be both instantiated on one platform. This patch updates
the Ids and names to make them unique from each other.
It should be noted that the I2C addresses for both PMIC and CODEC
are modifiable so instantiation of the two are kept as separate
devices, rather than instantiating the CODEC from the MFD code.

The PCM512x devices use a paged register map covering the entire register
range. Implement support for this, mapping pages in at addresses starting
at 0x100 for ease of use (though since the pages are numbered from 0 there
is going to be an off by one when looking at the first byte as a page
number).
Also mark the new registers as accessible with the exception of the
coefficient RAM which is a bit fiddly and may benefit from some extra
handling to linearise the blocks.

The PCM512x devices are a family of monolithic CMOS integrated circuits
that include a stereo digital-to-analog converter and additional support
circuitry.

Currently only slave clocking modes with automatic clock configuration
are supported and most of the DSP configuration for the device is not

SNDRV_PCM_RATE_KNOT means that the device can support rates that can not be
expressed using the rate bits. The driver will provide a list of those rates
specified through constraints. Any rate bits that are set in the rates mask will
be ignored. So setting other rate bits besides SNDRV_PCM_RATE_KNOT wont have any
effect, but might be confusing to the casual reader, so remove them.

Now that we have a generic card driver we can't rely on the card driver
selecting the CODECs for us so make the CODECs that can be enabled with
OF directly selectable in Kconfig. For the platforms not using OF it's
not clear that we don't still want to have some board specific selection
since the kernel needs to contain code to register the devices; ACPI could
provide this from firmware does not yet support any kind of generic card.
It may also be desirable to hide these if OF is not enabled to reduce
noise.
