In preparation to adopting a better, more comprehensive approach to
adding the coverage that was just added using some changes from Jaroslav
which were sent at the same time the recently added improvements were
being applied drop what was applied. This reverts:
7d721baea138 "kselftest/alsa: Add more coverage of sample rates and channel counts"
ee12040dd53a "kselftest/alsa: Provide more meaningful names for tests"
ae95efd9754c "kselftest/alsa: Don't any configuration in the sample config"
8370d9b00c92 Revert "kselftest/alsa: Report failures to set the requested channels as skips"
f944f8b539ea "kselftest/alsa: Report failures to set the requested sample rate as skips"
22eeb8f531c1 "kselftest/alsa: Refactor pcm-test to list the tests to run in a struct"

From: Jaroslav Kysela <perex@perex.cz>
Obtain all test parameters from the configuration files. The defaults
are defined in the pcm-test.conf file. The test count and parameters
may be variable per specific hardware.
Also, handle alt_formats field now (with the fixes in the format loop).
It replaces the original "automatic" logic which is not so universal.
The code may be further extended to skip various tests based
on the configuration hints, if the exact PCM hardware parameters
are not available for the given hardware.

Rather than allowing the system specific tests to replace the default set
of tests instead run them in addition to the standard set of tests. In
order to avoid name collisions in the reported tests we add an additional
test class element to the reported tests. Doing this means we always get a
consistent baseline of coverage no matter what card we run on but retain
the ability to specify specific coverage for a given system.

Since we don't know what the capabilities of an unknown card is any of our
standard tests may fail due to not being supported by the system. Set a
flag once we've configured the stream, just before we start data, to say
that the system accepted our stream configuration.
Since there shouldn't be a use case for tests that are specified for the
individual system failing for those tests we also add a new test which
fails if we are unable to configure the settings specified in the system
specific configuration file.

In order to help with the comprehensibility of tests it is useful for us to
document what the test is attempting to cover. We could just do this through
comments in the configuration files but in order to aid people looking at
the output of the program in logs let's provide support for an optional
'description' directive which we log prior to running each of the tests.

Add more coverage to our standard test cases:
- 8kHz mono and stereo to verify that the most common mono format is
clocked correctly.
- 44.1kHz stereo to verify that this different clock base is generated
accurately.
- 48kHz 6 channel to verify that 6 channel is clocked correctly.
- 96kHz stereo since that is a common audiophile rate.
