The buffers should be cleared when possible but we also don't want
buffer creation to fail in the rare case where the ring isn't ready
during the call. This could happen during some suspend/resume sequences.

The dumb_create API isn't intended for high performance rendering
and it's more useful for userspace (ie. IGT) to have them precleared.
The bonus here is that we also won't needlessly leak whatever was
previously in VRAM, but it also probably wasn't sensitive if it was
going through this API.

Add new member flags which will control the ras work flow.
For now, vbios enable ras for us on boot. That might change in the
future.
So there should be a flag from vbios to tell us if ras is enabled or not
on boot. Looks like there is no such info now.
Other bits of the flags are reserved to control other parts of ras.
