OMAPFB: Map interlace field in omap_video_timings with fb vmode flags

Use the interlace field in omap_video_timings to configure/retrieve
corresponding fb mode flags in fb_var_screeninfo and fb_videomode.

The interlace field maps with the fb mode flags FB_VMODE_INTERLACED and
FB_VMODE_NONINTERLACED.
