Haswell/falco/peppy/slippy: continue to clean up FUI.

As a first step towards removing hardcodes from the FUI support,
change the haswell call to i915_lightup to panel_lightup, and pass the
intel_dp * as a parameter. Get rid of the scalar arguments and make
them part of intel_dp. Get rid of file-scope variables and use the
ones in the intel_dp struct. In falco, use functions that peppy
uses. Drop slippy support for FUI, it's a dead board; if this is ok
I'll remove the files next.

And, incidentally, fix the broken RGBX constant and change it to BGRX.
