Add callbacks to the radeon_asic struct to handle
rptr/wptr fetchs and wptr updates.
We currently use one version for all rings, but this
allows us to override with a ring specific versions.
Needed for compute rings on CIK.

Register audio callbacks for asic where we support
audio. Cleans up the code and makes it easier to
add support for newer asics.

For large VM page table updates, we can sometimes generate
more packets than there is space on the ring. This happens
more readily with the DMA ring since it is 64K (vs 1M for the
CP). For now, switch back to the CP. For the next kernel,
I have a patch to utilize IBs for VM PT updates which
alleviates this problem.

although both formats seem to work ok.
- r7xx doesn't have the count multiple of 2 limitation.

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
