The compute rings use RELEASE_MEM rather then EOP
packets for writing fences and there is no SYNC_PFP_ME
packet on the compute rings.
Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

Type 2 packets are deprecated on CIK MEC and we should use
type 3 nop packets.  Setting the count field to the max value
(0x3fff) indicates that only one dword should be skipped
like a type 2 packet.

On CIK, the compute rings work slightly differently than
on previous asics, however the basic concepts are the same.

The main differences:
- New MEC engines for compute queues
- Multiple queues per MEC:
  - CI/KB: 1 MEC, 4 pipes per MEC, 8 queues per pipe = 32 queues
  -    KV: 2 MEC, 4 pipes per MEC, 8 queues per pipe = 64 queues
- Queues can be allocated and scheduled by another queue
- New doorbell aperture allows you to assign space in the aperture
  for the wptr which allows for userspace access to queues

v2: add wptr shadow, fix eop setup
v3: fix comment
v4: switch to new callback method

The doorbell aperture is a PCI BAR whose pages can be
mapped to compute resources for things like wptrs
for userspace queues.

This patch maps the BAR and sets up a simple allocator
to allocate pages from the BAR.

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.
