suspend/resume on Skylake (Lenovo T460s) with FreeBSD11 stable

[K. Macy]

You need a graphics driver that supports suspend. That's only going to be
i915. Right now suspend / resume doesn't work in drm-next-4.7 for anything
newer than Broadwell.

Your two choices for Skylake are either to debug the issue in drm-next or
add suspend / resume to sc or VT. I'm assuming that if the latter were easy
someone would already have done it.
