drm/mgag200: g200se: Set hiprilvl from DRM format

Replace the deprecated cpp field from struct drm_format_info with the
format's 4CC code when setting the hiprilvl field in CRTCEXT6.

Using a bpp of 32 for RGB888 is a bit dubious, but we keep it for now
to avoid changing behavior. Otherwise, bpp could also be retrieved by
calling drm_format_info_bpp().
