net: systemport: add suspend and resume support

Browse source

Implement the hardware recommended suspend/resume procedure for
SYSTEMPORT. We leverage the previous factoring work such that we can
logically break all suspend/resume operations into disctint RX and TX
code paths.

When the system enters S3, we will loose all register contents, so
make sure that we correctly re-program all the hardware and software
views of the RX & TX rings as well.
