[Nouveau] [PATCH 1/4] nouveau: Allow allocating BOs at specific offsets
We want to be able to guarantee the location of the allocated buffer
object if we're going to be able to reliably allocate the existing
framebuffer at startup. Add an argument to do so and pass that through to
the ttm core.

[Nouveau] [PATCH 3/4] nouveau: Reorder instmem init and generic vram setup
The instmem setup code may allocate from the region that's currently being
scanned out, but we can't allocate a buffer object to cover that until the
generic vram code has been run. Flip the order to make this possible.

[Nouveau] [PATCH 4/4] nouveau: Allocate existing framebuffers on nv50
Performing a flicker-free boot involves being able to ensure that we don't
write to the memory that's currently being scanned out, which means we need
to be able to allocate a block that matches the current framebuffer in
order to prevent that. This adds support for reading out the current
framebuffer state on nv50 and avoids graphical glitches appearing during
modesetting.
