Phy: DT binding documentation for Marvell MVEBU SATA phy.

Browse source 
Describe the binding for the Marvell MVEBU SATA phy. This driver
can be used at least with Kirkwood, Dove and maybe others.
Additionally, update the SATA binding with the properties to link
to the phy nodes.

* Marvell MVEBU SATA PHY
Power control for the SATA phy found on Marvell MVEBU SoCs.
This document extends the binding described in phy-bindings.txt
Required properties :
- reg : Offset and length of the register set for the SATA device
- compatible : Should be "marvell,mvebu-sata-phy"
- clocks : phandle of clock and specifier that supplies the device
- clock-names : Should be "sata"
Example:
sata-phy@84000 {
compatible = "marvell,mvebu-sata-phy";
reg = <0x84000 0x0334>;
clocks = <&gate_clk 15>;
clock-names = "sata";
#phy-cells = <0>;
status = "ok";
};
