OMAPDSS: convert pixel clock to common videomode style
omapdss has its own video-timings struct, but we want to move the common videomode. The first step is to change the omapdss's pixelclock unit from kHz to Hz. Also, omapdss uses "pixel_clock" field name, whereas the common videomode uses "pixelclock" field name. This patch changes the field name also, as that makes it easy to spot any non-converted pixel_clock uses. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
