net: phy: adin: implement downshift configuration via phy-tunable Down-speed auto-negotiation may not always be enabled, in which case the PHY won't down-shift to 100 or 10 during auto-negotiation. This change enables downshift and configures the number of retries to default 4 (which is also in the datasheet The downshift control mechanism can also be controlled via the phy-tunable interface (ETHTOOL_PHY_DOWNSHIFT control). The change has been adapted from the Aquantia PHY driver.
