[Intel-gfx] [PATCH v2 1/2] drm: Add Panel Self Refresh DP addresses

Add the addresses and definitions I care about for Panel Self Refresh, as
documented in the eDP spec.
I'm sending these out before some other patches because this should be a fairly
simple one to get upstream and not require too much fuss (where the others may
have some fuss).
This file is a mess with white spacing. I tried to stay consistent with the
surrounding code.
v2: had some silly mistakes in v1 which Keith caught
