The only difference seems to be in the slightly different CB tuning limit. Note that PLL_REF_INPUT_TVCLKINBC is a reserved value on ilk+. Also strictly speaking we don't support native TV-out on ilk+, hence all that code is dead. But Bspec still contains some residual mentions of native TV-out on some pch-split platforms, so I've figured it doesn't hurt to keep the code around a bit longer (e.g. in the cb tune function). v2: Improve the commit message as Jani suggested in his review.
