To conform to DRM's new API, we should not be accessing a DRM object's
internal state directly. Rather, the DRM for_each_old/new_* iterators,
and drm_atomic_get_old/new_* interface should be used.

This is an ongoing process. For now, update the DRM-facing atomic
functions, where the atomic state object is given.

Use the correct for_each_new/old_* iterators instead of for_each_*

The following functions were considered:

amdgpu_dm_find_first_crtc_matching_connector: use for_each_new
    - Old from_state_var flag was always choosing the new state

amdgpu_dm_display_resume: use for_each_new
    - drm_atomic_helper_duplicate_state is called during suspend to
      cache the state
    - It sets 'state' within the state triplet to 'new_state'

amdgpu_dm_commit_planes: use for_each_old
    - Called after the state was swapped (via atomic commit tail)

amdgpu_dm_atomic_commit: use for_each_new
    - Called before the state is swapped

amdgpu_dm_atomic_commit_tail: use for_each_old
    - Called after the state was swapped

dm_update_crtcs_state: use for_each_new
    - Called before the state is swapped (via atomic check)

amdgpu_dm_atomic_check: use for_each_new
    - Called before the state is swapped

v2: Split out typo fixes to a new patch.

v3: Say "functions considered" instead of "affected functions". The
    latter implies that changes are made to each.

Initial pull request for DC support.  We've completed a substantial amount of
the cleanup and restructuring in our TODO.  There are a few additional
cleanups that we are continuing to work on, but I don't think there are any
showstoppers remaining. We've tried to maintain most of the history for bisect
purposes.  Harry made sure all the commits build.  We've enabled DC for vega10
and Raven.  Pre-vega10 parts can be enabled via module parameter (amdgpu.dc=1),
but are not enabled by default at this point until we get further testing
upstream.

This code provides atomic modesetting support for DCE8 (CIK), DCE10 (Tonga,
Fiji), DCE11 (CZ, ST, Polaris), DCE12 (vega10), and DCN1 (RV) including
HDMI and DP audio, DP MST, and many other advanced display features.

Latest cleanups for DC from you and Harry.  Note that there is some
flickering on some older asics with this branch due to a regression in powerplay
that has already been fixed and will be included in my next non-DC pull request
next week.

Highly concurrent Piglit runs can trigger a race condition where a pending
SDMA job on a buffer object is never executed because the corresponding
process is killed (perhaps due to a crash). Since the job's fences were
never signaled, the buffer object was effectively leaked. Worse, the
buffer was stuck wherever it happened to be at the time, possibly in VRAM.

The symptom was user space processes stuck in interruptible waits with
kernel stacks like:
