drm/i915: pnv dpll doesn't use m1!

So don't try to store it in the DPLL_FP register.

Otherwise it looks like the limits for pineview are correct: It has
it's own clock computation code, which doesn't use an offset for n
divisors, and the register value based m limits look sane enough.

v2: Rebase on top of the pineview clock refactor and fixup up the
commit message: It's m1 pnv doens't care about, not m2!

Quoting Damien's review:

  - "n can vary between 2 and 6, but we declare the 3-6 as limits.
  - "p1 seems to be able to go up to 9
  - "the m upper limit seems a bit big, but the docs are a bit shy on
    that values for pnv.

"Otherwise, the change itself seems good:"
