_DCS, _DGS and _DSS are required by specification. However,
we never implemented them properly, and no OS driver com-
plained yet. So we stub them out and keep the traditional
behavior in case an OS driver checks for their existence.
The old implementations also only returned static values as
there never was any write to their GNVS variables. The TRAP()
that was called in one place is actually implemented by some
ThinkPad's SMI handler as docking event. However, as the call
precedes these SMI handlers in coreboot history, it's most
likely an accident.

As discussed on the mailing list and voted upon, the coreboot project
is going to move the majority of copyrights out of the headers and into
an AUTHORS file. This will happen a bit at a time, as we'll be unifying
license headers at the same time.
Updated Authors file is in a separate commit.

* Mark existing code as legacy
(still required if no GMA driver is running)
* Call legacy code if Mailbox 3 is unsupported, on error or
if gma driver isn't running
Tested on Lenovo T430:

It encourages users from writing to the FSF without giving an address.
Linux also prefers to drop that and their checkpatch.pl (that we
imported) looks out for that.
This is the result of util/scripts/no-fsf-addresses.sh with no further
editing.

Consolidate some common (and mostly broken) code. Will try to fix things
in separate commits.
Maybe, igd.asl taken from gm45 (the non-PCH case) could also be used for
i945 and sch. But this needs further investigation.
