The ilk+ disable_lp_wm boolean has the exact same role as
disable_cxsr for gmch platforms. The documentation also
still talks about CxSR on ilk+ even theough the way you
control it has now change to involve toggling the LP watermarks.
Get rid of disable_lp_wm and just use disable_cxsr for ilk+
as well.
TODO: Unify even more to not have any gmch vs. ilk+
details in high level modeset code...
