We probably need special handling for the case spi->max_speed_hz
is smaller than CS35L41_SPI_MAX_FREQ_OTP here, in that case this
code would increase the SPI speed. If the max speed was set lower
that is probably because something other than the amp in the
system limits it. Track length or the host or something.

The default needs to be updated to match the register patch here.
regmap_register_patch does a bypassed write so the default should
be set to the patched value.

There are a bunch of registers with status/sts in the name in here with
defaults, normally you wouldn't want a default for a status register,
since it would be a volatile register. Are we sure these are
correct?

Probably worth explaining why you want to do this through ALSA
controls rather than set_tdm/set_channel_map.

Is this necessary I think ASoC handles this internally since the
regmap is already on the CODEC device?
