The only bpc information in pipe registers for BXT/GLK DSI is the PIPEMISC dither bpc. Let's try to use that to read out pipe_bpp on these platforms. However, I'm not sure if this will be correctly populated by the GOP since bspec suggests it's only needed if dithering is actually enabled. If not I guess we'll have to go one step further and extract pipe_bpp from the DSI pixel format when dithering is disabled.
