[Intel-gfx] [PATCH] drm/i915: Set i9xx lvds clock limits according to specifications

[Patrik Jakobsson]

The Intel PRM says the M1 and M2 divisors must be in the range of 10-20 and 5-9.
Since we do all calculations based on them being register values (which are
subtracted by 2) we need to specify them accordingly.
