[Intel-gfx] [PATCH 4/9] drm/i915: fixup g4x pll limits

[Daniel Vetter]

Again the same confusion that our code expects m1/m2 in register values.
This time around with the added fun that many of the existing values
have been all off by a bit in different directions. Hence extract a
common #define.

Note that n limits differ between lvds and other outputs. Strangely they've
all been correct already.

v2: Rebased on top of the DP pll rework, which makes it even more
obvious that we can do this ...
