radv/gfx10: use L2 for DMA copy/fill operations
It's coherent and faster. GFX7-GFX9 should also support this but
for now only uses L2 for GFX10 because it's untested on previous gens.
This fixes dEQP-VK.memory.pipeline_barrier.transfer_*
This also fixes some missing geometry in Dawn Of War III because
VBOs weren't updated correctly.
