[PATCH v1 4/4] net/axgbe: fix SGMII autoneg status bits

The SGMII autonegotiation status bit definitions do not match the
hardware specification. The link status and duplex bits are defined
at incorrect positions, which can lead to incorrect link state and
duplex reporting.

Correct the SGMII autoneg status bit definitions to align with the
hardware specification.
