drm/i915: Account for scale factor when calculating initial phase
To get the initial phase correct we need to account for the scale
factor as well. I forgot this initially and was mostly looking at
heavily upscaled content where the minor difference between -0.5
and the proper initial phase was not readily apparent.
And let's toss in a comment that tries to explain the formula
a little bit.
v2: The initial phase upper limit is 1.5, not 24.0!
