[PATCH] [RFC] drm/etnaviv: Disable softpin

[Marek Vasut]

Currently softpin suffers from assorted race conditions exposed by newer
versions of mesa 22.2.y and 22.3.y . Those races are difficult to fix in
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.
