ASoC: Don't oops in soc_probe_aux_dev in case of missing codec

Blind copy of codec finding algorithm from soc_bind_dai_link does not work
in soc_probe_aux_dev if matching codec name is not found. In that case the
code falls through and tries to start the probing procedure with invalid
codec pointer.

Fix this and add an error print showing the codec name that cannot be found.

ASoC: Fix inconsistent meaning of default case while checking alc5623->id

In alc5623_i2c_probe(),
the default case for checking alc5623->id behaves the same as case 0x23.
However, In alc5623_probe() the default case for checking alc5623->id
becomes to be the same as case 0x21.
This makes the meaning of default case inconsistent.

Since we have checked codec id in alc5623_i2c_probe() by comparing
vid2 with id->driver_data, it is not possible to run into the default case now.

In case we may add more supported devices to alc5623_i2c_table in the future,
this patch changes the default case return -EINVAL to let people know that
they should not run into this case. They should also add a new case accordingly
for the new id.

ASoC: Add support for optional auxiliary dailess codecs

This makes possible to register auxiliary dailess codecs in a machine
driver. Term dailess is used here for amplifiers and codecs without DAI or
DAI being unused.

Dailess auxiliary codecs are kept in struct snd_soc_aux_dev and those codecs
are probed after initializing the DAI links. There are no major differences
between DAI link codecs and dailess codecs in ASoC core point of view. DAPM
handles them equally and sysfs and debugfs directories for dailess codecs
are similar except the pmdown_time node is not created.

Only suspend and resume functions are modified to traverse all probed codecs
instead of DAI link codecs.

Example below shows a dailess codec registration.

struct snd_soc_aux_dev foo_aux_dev[] = {
{
.name = "Amp",
.codec_name = "codec.2",
.init = foo_init2,
},
};

static struct snd_soc_card card = {
...
.aux_dev = foo_aux_dev,
.num_aux_devs = ARRAY_SIZE(foo_aux_dev),
};

mfd: Add initial WM8958 support

The WM8958 is a derivative of the WM8994 which is register compatible
with the addition of some extra features, mostly in the CODEC side.
The major change visible at the MFD level is that rather than a single
DBVDD supply we now have three separate DBVDDs so we must request and
enable a different set of supplies.
