[deathsimple/drm-next-3.16][PATCH V3 3/4] drm/radeon/hdmi: DCE2: update setmode

Recent RE efforts revealed ops performed by fglrx during HDMI setup.
This mostly adds masks to r/w ops plus few single missing bits.
This has been tested for possible regressions on:
1) DCE2 HD2400 (RV610)
2) DCE3 HD3470 (RV620)
For a reference and details see:

V2: Move r600d.h changes to 0003 (from 0004) to don't break compilation
Fix typo in commit message
Leave comment about DCE 3.0 and ACR control
V3: Rebase
