drm/sti: hdmi fix CEA-861E video format timing error

Browse source 
HDMI analyzer tests showed that Vsync and Hsync signal were not
compliant with the HDMI protocol.

The first active pixel of a line is defined by HDMI_ACTIVE_VID_XMIN.
The last active pixel of a line is defined by HDMI_ACTIVE_VID_XMAX.
