drm: sti: add VTG driver Video Time Generator drivers are used to synchronize the compositor and tvout hardware IPs by providing line count, sample count, synchronization signals (HSYNC, VSYNC) and top and bottom fields indication. VTG are used by pair for each data path (main or auxiliary) one for master and one for slave.
