Move the S3C_FB_MAX_WIN to the platform data to avoid having to include the registers with the platform data. Set S3C_FB_MAX_WIN to 5, which is the maximum that any of the current hardware can do and the cost of having it set to this for all is minimal (at least for the platform data case), then always leave this as the maximum for the systems supported. Also remove the inclusion of <mach/regs-fb.h> from the device definition in arch/arm/plat-samsung Signed-off-by: Ben Dooks <ben-linux@fluff.org>
