[coreboot-gerrit] Change in libgfxinit[master]: gma bdw+ transcoder: Use always-on path for primary pipe on eDP

[Nico Huber (Code Review)]

Hello Matt DeVillier,

I'd like you to reexamine a change. Please visit

to look at the new patch set (#2).

gma bdw+ transcoder: Use always-on path for primary pipe on eDP

This was a mistake in abb16d9 (gma hsw transcoder: Choose PDW path for
scaling on DDI A). We only have to do it on HSW, future CPUs support
scaling on the always-on path and don't support the alternative path
anymore.

Tested on Haswell (gfx_test), Broadwell (gfx_test) and Coffee Lake
(gfx_test & coreboot).
