Subject: [PATCH] drm/i915/vlv: use correct units for rc6 residency v2

We need to use the clock control reg to figure out how many CZ clks are in
30ns and use that as the basis for our RC6 residency calculations.

v2: use ULL everywhere for consistency (Chris)
    factor out bias for clarity (Chris)
