Lendacky, Thomas d7445d1f05 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.

Lendacky, Thomas a64def4161 amd-xgbe: Prepare for introduction of clause 37 autoneg
Prepare for the future introduction of clause 37 auto-negotiation by
updating the current auto-negotiation related functions to identify
them as clause 73 functions. Move interrupt enablement to the
enable/disable auto-negotiation functions. Update what will be common
routines to check for the current type of AN and process accordingly.
