drm/radeon/kms: add evergreen/cayman CS parser for async DMA (v2)
Allows us to use the DMA ring from userspace.
DMA doesn't have a good NOP packet in which to embed the
reloc idx, so userspace has to add a reloc for each
buffer used and order them to match the command stream.
v2: fix address bounds checking
