The normal bo cache uses some intermediate steps between power of two
jumps to reduce memory wastage. But for a ringbuffer bo cache, we do
not need this.

With a new enough drm/msm, we can let the kernel know about buffers that
are in the bo cache, so the kernel can free them under memory pressure.
