drm: Add drm_fixp_from_fraction and drm_fixp2int_ceil

2016-02-05T05:23:48Z

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.

Sign bit wasn't handled properly and a small typo. Thanks to Christian for helping me sort this out. Signed-off-by: Alex Deucher
