powerpc/hydra: Add ethernet support on P5020/P3041 DS boards

Add support for RGMII, SGMII, and XAUI (10Gb) Ethernet on P3041DS &
P5020DS ("Hydra").

The lane_to_slot[] array is initialized dynamically, since board switches
can be used to control the muxing of SERDES lanes to slots.

The BRDCFG1 PIXIS register is used to route the MII bus to the appropriate
slot.  The SERDES configuration is queried to help determine the routing
between MACs and slot/phy combination.

If a XAUI card is inserted, muxing for that card is enabled and never
turned off.  The PHY address for the 10G XAUI card depends on the slot in
which it's inserted.  If it's in slot 1, the address is 4.  If it's in
slot 2, the address is 0.

Update the MDIO routing in the P3041DS and P5020DS device trees based on
the board-level muxing.  The SERDES configuration determines which
SGMII/XGMII boards are located in which slots, and so the MDIO bus needs
to be muxed correctly whenever talking to a PHY connected to any Fman MAC.
The Fman Ethernet nodes in the device tree also need to be routed to the
correct PHYs.

Removed CONFIG_SYS_FMAN_FW as its not used anywhere.

+ * This file handles the board muxing between the Fman Ethernet MACs and
+ * the RGMII/SGMII/XGMII PHYs on a Freescale P3041/P5020 "Hydra" reference
+ * board. The RGMII PHYs are the two on-board 1Gb ports.  The SGMII PHYs are
+ * provided by the standard Freescale four-port SGMII riser card.  The 10Gb
+ * XGMII PHY is provided via the XAUI riser card.  Since there is only one
+ * Fman device on a P3041 and P5020, we only support one SGMII card and one
+ * RGMII card.
+ *
+ * Muxing is handled via the PIXIS BRDCFG1 register.  The EMI1 bits control
+ * muxing among the RGMII PHYs and the SGMII PHYs.  The value for RGMII is
+ * always the same (0).  The value for SGMII depends on which slot the riser is
+ * inserted in.  The EMI2 bits control muxing for the the XGMII.  Like SGMII,
+ * the value is based on which slot the XAUI is inserted in.
+ *
+ * The SERDES configuration is used to determine where the SGMII and XAUI cards
+ * exist, and also which Fman MACs are routed to which PHYs.  So for a given
+ * Fman MAC, there is one and only PHY it connects to.  MACs cannot be routed
+ * to PHYs dynamically.
+ *
+ *
+ * This file also updates the device tree in three ways:
+ *
+ * 1) The status of each virtual MDIO node that is referenced by an Ethernet
+ *    node is set to "okay".
+ *
+ * 2) The phy-handle property of each active Ethernet MAC node is set to the
+ *    appropriate PHY node.
+ *
+ * 3) The "mux value" for each virtual MDIO node is set to the correct value,
+ *    if necessary.  Some virtual MDIO nodes do not have configurable mux
+ *    values, so those values are hard-coded in the DTS.  On the HYDRA board,
+ *    the virtual MDIO node for the SGMII card needs to be updated.
+ *
+ * For all this to work, the device tree needs to have the following:
+ *
+ * 1) An alias for each PHY node that an Ethernet node could be routed to.
+ *
+ * 2) An alias for each real and virtual MDIO node that is disabled by default
+ * and might need to be enabled, and also might need to have its mux-value
+ * updated.
