nb/intel/x4x: Implement resume from S3 suspend
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).
