drm/omap: Add infoframe & dvi/hdmi mode support
Make the omapdrm driver use the new HDMI ops when possible.
omapdrm will call set_hdmi_mode (when available) to tell the encoder
driver whether the monitor is a DVI or HDMI monitor, and if it's an HDMI
monitor, omapdrm will call set_hdmi_infoframe to to set the AVI
infoframe.
