There is no corresponding invalidate call before the buffer is written
to, this results in screen freezing sometime after switching to console
mode with PSR enabled. Invalidating the front buffer in the fbdev call
backs won't work either as some of them are called in atomic contexts and
{drrs, fbc, psr}_invalidate all sleep. So don't activate PSR for now.
