use gtt for firmware buffers

I still don't understand what's corrupting the cpu pointer.  Ultimately, it
looks like the GPU does not power up correctly after powering down so the
segfault is largely irrelevant.  Does this patch help? memcpy_toio is required
for accessing memory mapped device resources (e.g., vram) on some platforms. 
x86 doesn't matter.
