[PATCH v4 0/7] kselftest/alsa: pcm-test improvements

[Mark Brown]

This series provides a bunch of quick updates which should make the
coverage from pcm-test a bit more useful, it adds some support for
skipping tests when the hardware/driver is unable to support the
requested configuration, support for providing user visible descriptions
and then expands the set of cases we cover to include more sample rates
and channel counts.  This should exercise switching between 8kHz and
44.1kHz based rates and ensure that clocking doesn't get confused by
non-stereo channel counts, both of which are I expect common real world
errors, at least for embedded cards.

v4:
 - Rebase onto v6.2-rc1.
v3:
 - "Rebase" onto Takashi's current tree (with a revert).
 - Include Jaroslav's changes to specify all tests in the configuration
   file parsing.
 - Add a new "description" field to the configuration instead of trying
   to name the tests.
 - Always run both default and per-system tests, logging our success at
   setting the per-system configurations as a separate test since they
   shouldn't fail.
v2:
 - Rebase onto Takashi's current tree.
 - Tweak the buffer sizes for the newly added cases, don't be quite
   so ambitious in how big a buffer we request for 96kHz and don't
   go quite so small for 8kHz since some devices start hitting lower
   limits on period size and struggle to deliver accurate timing.
