[PATCH net-next v3 4/5] net: macb: rename bp->sgmii_phy field to bp->phy

["Théo Lebrun" <theo.lebrun@bootlin.com>]

The bp->sgmii_phy field is initialised at probe by init_reset_optional()
if bp->phy_interface == PHY_INTERFACE_MODE_SGMII. It gets used by:
 - zynqmp_config: "cdns,zynqmp-gem" or "xlnx,zynqmp-gem" compatibles.
 - mpfs_config: "microchip,mpfs-macb" compatible.
 - versal_config: "xlnx,versal-gem" compatible.

Make name more generic as EyeQ5 requires the PHY in SGMII & RGMII cases.

Drop "for ZynqMP SGMII mode" comment that is already a lie, as it gets
used on Microchip platforms as well. And soon it won't be SGMII-only.
