Florian Fainelli d06f78c423 net: phy: broadcom: Add support code for downshift/Wirespeed
Broadcom's Wirespeed feature allows us to configure how auto-negotiation
should behave with fewer working pairs of wires on a cable. Add support
code for retrieving and setting such downshift counters using the
recently added ethtool downshift tunables.
