Subject: [PATCH net-next V3 1/2] net: phy: micrel: Add KS8851 PHY support

The KS8851 has a reduced internal PHY, which is accessible through its
registers at offset 0xe4. The PHY is compatible with KS886x PHY present
in Micrel switches, including the PHY ID Low/High registers swap, which
is present both in the MAC and the switch.

V2: Merge the KSZ8851 and KS886X entries, as those PHYs cannot be discerned
V3: Add RB from Andrew
