drm/i915: rename CNP_RAWCLK_FRAC to CNP_RAWCLK_DEN
Although CNP names this field "Counter Fraction", what we write to the register is really the denominator for the fractional part of the divider, not the fractional part (and the field description even says that). The ICP spec renamed the field to "Counter Fraction Denominator", which makes a lot more sense. Use the more complete ICL naming because we will merge the CNP and ICP functions into a single one, which will introduce the concept of the numerator. That will make a lot more sense when you read the "num/frac = den" calculation.
