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.

Better just use for_each_new_old here, so you can get both old and new 
from the iterator.

Why did you switch to for_each_old iterator here ? if you use the 
for_each_new
iterator you can get rid of new_acrtc_state = 
to_dm_crtc_state(pcrtc->state);
and just use the iterator's state

Same as above
