drm: Add drm_fixp_from_fraction and drm_fixp2int_ceil
commit 64566b5e767f9bc3161055ca1b443a51afb52aad upstream.
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.
