Enable a workaround to avoid I/O bursts within the mgag200 driver at
the expense of overall display performance.
It restores the <v5.10 behavior, by mapping the framebuffer in system
RAM as Write-Combining, and flushing the cache after each write.
This is only useful on x86_64 if you want to run processes with
deterministic latency.
If unsure, say N.
