Harry Wentland	64566b5e76	drm: Add drm_fixp_from_fraction and drm_fixp2int_ceil ... drm_fixp_from_fraction allows us to create a fixed point directly from a fraction, rather than creating fixed point values and dividing later. This avoids overflow of our 64 bit value for large numbers. drm_fixp2int_ceil allows us to return the ceiling of our fixed point value.
