amd-xgbe: Add support for a KR redriver
This patch provides support for the presence of a KR redriver chip in
between the device PCS and an external PHY. When a redriver chip is
present the device must perform clause 73 auto-negotiation in order to
set the redriver chip for the downstream connection.
