2017-02-17nb/intel/x4x: Implement resume from S3 suspendArthur Heymans
It rewrites the results of receive enable stored in the upper nvram region, to avoid running receive enable again. Some debug info is also printed about the self-refresh registers. (Not enforcing a reset here, since 0 does not necessarily mean it's not in self-refresh).

2016-09-07nb/intel/x4x: Fix DMI initDamien Zammit
No more hang on DMI init when wait for DMI is re-enabled. Previously the virtual channel arbitration table was not being set up in the south/north bridges causing invalid DMI state. This has been tested on GA-G41M-ES2L with patches following. An NVIDIA GT218 card was detected by the OS and displayed using the nouveau driver with no blobs.

2016-05-31nb/intel/x4x: Add DMI/EP initDamien Zammit
The values were obtained from vendor bios at runtime. I am not 100% sure of the sequence required to initiate them, but guessed from the gm45 code. There may be some status bytes needed to be polled during the sequence that is missing, but as I don't have bios writer's datasheet it's very hard for me to know.
