New repository created for platform-specific test parametrization

Hi All,

I'm writing this to let you know that a new repository has been created under
the KernelCI organization, called 'platform-test-parameters' [1]. Its purpose is
to hold the information that is needed to run tests parametrized for a specific
platform.

As one example, the discoverable devices probe kselftest [2] that is upstream
requires a platform-specific file to describe the devices to test for, but those
files can't be stored upstream and need to be supplied from elsewhere. Thus this
new repository now stores the files for a few different platforms, allowing us
to run the test on those platforms [3].

While we should strive to have the upstream tests be as generic as possible,
some platform-specific information is sometimes needed. I hope this repository
will serve as a way for us to collaborate on the platform-specific data, not
only to collect and maintain it, but also to standardize the format of such data
and even help drive the upstream test engineering to use agreed upon formats.

Thanks,
Nícolas
