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.

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.

The ASoC core has now been changed to default to the non-legacy DAI
naming, as such drivers using the new scheme no longer need to specify
the non_legacy_dai_naming flag.

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.
