ASoC: nau8821: Improve AMIC recording performance.

Since the hardware may be designed as a single-ended input, the headset mic
record only supports single-ended input on the left side. This patch
will enhance microphone recording performance for single-end.

ASoC: nau8821: Add DMI quirk mechanism for active-high jack-detect

Add a quirk mechanism to allow specifying that active-high jack-detection
should be used on platforms where this info is not available in devicetree.

And add an entry for the Positivo CW14Q01P-V2 to the DMI table, so that
jack-detection will work properly on this laptop.

ASoC: Switch i2c drivers back to use .probe()

After commit b8a1a4cd5a98 ("i2c: Provide a temporary .probe_new()
call-back type"), all drivers being converted to .probe_new() and then
03c835f498b5 ("i2c: Switch .probe() to not take an id parameter") convert
back to (the new) .probe() to be able to eventually drop .probe_new() from
struct i2c_driver.

ASoC: nau8821: Implement hw constraint for rates

nau8821 driver restricts the sample rate with over sampling rate, but
currently it barely bails out at hw_params with -EINVAL error (with a
kernel message); this doesn't help for user-space to recognize which
rate can be actually used.

This patch introduces the proper hw constraint for adjusting the
available range of the sample rate depending on the OSR setup, as well
as some code cleanup, for improving the communication with
user-space. Now applications can know the valid rate beforehand and
reduces the rate appropriately without errors.

ASoC: nau8821: Don't unconditionally free interrupt

The remove() operation unconditionally frees the interrupt for the device
but we may not actually have an interrupt so there might be nothing to
free. Since the interrupt is requested after all other resources we don't
need the explicit free anyway, unwinding is guaranteed to be safe, so just
delete the remove() function and let devm take care of things.

ASoC: nau*: Remove now redundant non_legacy_dai_naming flag

naming, as such drivers using the new scheme no longer need to specify
the non_legacy_dai_naming flag.

ASoC: nau8*: use simple i2c probe function

The i2c probe functions here don't use the id information provided in
their second argument, so the single-parameter i2c probe function
("probe_new") can be used instead.

This avoids scanning the identifier tables during probes.

While the code is not incorrect, we can deal with the out-of-bounds
check in a clearer way that makes static analysis happy.
