drm/sti: hdmi fix CEA-861E video format timing error
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. Signed-off-by: Vincent Abriou <vincent.abriou@st.com>
