This seems to be an impressive piece of copy&pasta lore. I've
checked all docs and on most platforms these bits are all MBZ, with
the exception of the SDVO pixel multiplier on gen3. On gen4 that
moved to a special DPLL_MD registers.
No indication whatsoever that we actually need this for native
TV-out support. I suspect this started as a hack when we didn't
yet have proper pixel multiplier support in place for SDVO TV, but
then got stuck in a life of its own.
Just rip it out.

TV-out uses the same reference clock as everyone else. 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).
