The FMT blocks control how data is sent from the backend
of the display pipe to to monitor.  Proper set up of the
FMT blocks are required for 30bpp formats.  Additionally,
dithering can be enabled on for better display with 18 and
24bpp displays.  The exception is LVDS/eDP which atom
takes care of in the SelectCRTC_Source table.  For now
just enable truncation until we test dithering more.

We need to allocate line buffer to each display when
setting up the watermarks.  Failure to do so can lead
to a blank screen.  This fixes blank screen problems
on dce8 asics.

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
