Lendacky, Thomas f047604a3f amd-xgbe: Update/fix 2.5GbE support
Update the amd-xgbe driver and phylib driver to better support
the 2.5GbE mode for the hardware. In order to be able establish
2.5GbE using clause 73 auto negotiation the device will support
speed sets of 1GbE/10GbE and 2.5GbE/10GbE.

* AMD 10GbE PHY driver (amd-xgbe-phy)
Required properties:
- compatible: Should be "amd,xgbe-phy-seattle-v1a" and
"ethernet-phy-ieee802.3-c45"
- reg: Address and length of the register sets for the device
- SerDes Rx/Tx registers
- SerDes integration registers (1/2)
- SerDes integration registers (2/2)
Optional properties:
- amd,speed-set: Speed capabilities of the device
0 - 1GbE and 10GbE (default)
1 - 2.5GbE and 10GbE
Example:
xgbe_phy@e1240800 {
compatible = "amd,xgbe-phy-seattle-v1a", "ethernet-phy-ieee802.3-c45";
reg = <0 0xe1240800 0 0x00400>,
<0 0xe1250000 0 0x00060>,
<0 0xe1250080 0 0x00004>;
amd,speed-set = <0>;
};
