nb/gm45/gma.c: Decode edid before doing native graphic init

This allows the EDID data to be used outside of the native graphic
init path without having to fetch it again.

This extends return values of decode_edid to make the distinction
between invalid EDID and 'not connected' EDID.

TESTED on Lenovo X200
