7f2d479c01 drm: sti: fix delay in VTG programming 
The HDMI path introduce a delay of 6 pixels.
This delay should be take into account while programming
VTG for the HDMI. Without this delay, the HDMI active
window area is shift of 6 pixel on the right.

Set also timing for DVO output.

and tvout hardware IPs by providing line count, sample count,
synchronization signals (HSYNC, VSYNC) and top and bottom fields

VTG are used by pair for each data path (main or auxiliary)
one for master and one for slave.
