This series of patches fix various issues in STI drm driver. Now HDMI i2c adapter could be selected in device tree and plug detection doesn't use gpio anymore. I also had fix some signal timing problems after testing the driver on more hardware. The remaining patches attemps to simplify the code and prepare the next evolutions like DVO and auxiliary CRTC support
