I didn't see how you confirmed that it was good data rather than just
conservative, power hungry values ;-) Nevertheless, getting eDP to light
up is a massive step forward on those machines.

Applied (after smoke testing on my non-eDP machines) to -next with some
minor amendments (style and compiler warnings).

Thanks Jesse, and to everyone who tested the various hacks, maybe there is
some light at the end of the eDP tunnel!
