[Intel-gfx] [PATCHv3] drm/i915: Support Async Flip on Linear buffers

[Arun R Murthy]

Intel Gen do support Async Flip is supported on linear buffers. Since we
didn't had a use case, it was not enabled. Now that as part of hybrid
graphics for unsupported hardware pixel formats, its being converted to
linear memory and then flipped, hence enabling!
This patch enables support for async on linear buffer.

v2: added use case
v3: enabled async on linear for pre Gen 12 as well
