1. FB bits are extended to u64 considering future platforms.
2. Warnings this changes fixes are given below. Issue is same fb object
is being displayed on
multiple sprite planes. Since there was no fb bit per sprite we hit
those warnings.
Since this patch extends the bits to all sprites warning does not appear.
