Remove "disable auto-negotiation" workaround for Marvell Alaska PHYs
This avoids an intermediate link state (10baseT) before the interface is configured via ifconfig(8), and is consistent with other MII drivers and OSes. The original reason for this workaround is mainly thought be related to either reducing the time required for auto-negotiation to complete or indeed incorrect advertisement of link capabilities. Tested on Intel Elkhart Lake with dwqe(4) and 88E1512 PHY. Originally from stsp@ with feedback from kettenis@. ok kettenis@ claudio@
