Can't we now remove the HAS_LPT check from assert_pch_pll? Afaics we only
call it from ilk_pch_transcoder_enable and from the pch_pll handling
functions, both of which should no longer be called from haswell code.

For renaming them, I think that particular problem will solve itself once
we move all the ilk-ivb crtc/pch code into it's own file. With all these
splits you've done here for vga, I don't see much common code between
older pch and new-style ddi pch any more ...
