Currently softpin suffers from assorted race conditions exposed by newer

older kernel versions due to massive amount of backports necessary to do
so. Disable softpin by default until Linux 6.1.y is out, which contains
the necessary fixes to make softpin work reliably.
Sorry, but that's a NACK. The userspace driver depends on softpin for
GPUs with texture descriptors, so this introduces a hard functional
regression for those GPUs. I.e. they would go from "require race fixes
that are already on the way to upstream" to not working at all.
I expected that NAK.
But then, what options do we have here, except for a massive convoluted
backport, which might bring bugs of its own ?
