From: Hawking Zhang <Hawking.Zhang@xxxxxxx>
GFX is the graphics and compute block on the GPU.
v1: add initial gfx v10 implementation (Ray)
v2: convert to new get_vm_pde function in emit_vm_flush (Hawking)
v3: switch to new emit ib interfaces (Hawking)
v4: squash in updates (Alex)
v5: remove unused variables (Alex)
v6: v6: some golden regs moved to vbios (Alex)
v7: squash in some cleanups (Alex)
v8: squash in golden settings update (Alex)
