Subject: [PATCH 00/13] ALSA: update sample rate definitions

This patchset adds rate definitions for 12kHz, 24kHz and 128kHz.

It is follow-up on the series/discussion [0] about adding 128kHz for
spdif/eARC support. The outcome was to add 12kHz and 24kHz as well and
clean up the drivers that no longer require custom rules to allow these
rates.

Identifying these drivers is not straight forward, I tried my best but I
may have missed some. Those will continue to work anyway so it is not
critical. Some drivers using these rates have not been changed on
purpose. The reason for this may be:
* The driver used other uncommon rates that still don't have a definition
  so a custom rule is still required.
* The constraint structure is used in some other way by the driver and
  removing it would not help the readability or maintainability. This is
  the case the freescale asrc drivers for example.

There is one change per driver so, if there is a problem later on, it will
easier to properly add Fixes tag.

The series has been tested with
* ARM64 defconfig - spdif 128kHz at runtime.
* x86_64 allmodconfig - compile test only

Last, the change adding IEC958 definitions has been dropped for this
patchset and will be resent separately
