devicetree: create a separate binding description for sata_highbank 



The Calxeda sata_highbank driver has been adding its descriptions to the
ahci driver. Separate them properly. This patch only affects
documentation and has no functional component.

* Calxeda AHCI SATA Controller



SATA nodes are defined to describe on-chip Serial ATA controllers.

The Calxeda SATA controller mostly conforms to the AHCI interface

with some special extensions to add functionality.

Each SATA controller should have its own node.



Required properties:

- compatible        : compatible list, contains "calxeda,hb-ahci"

- interrupts        : <interrupt mapping for SATA IRQ>

- reg               : <registers mapping>



Optional properties:

- dma-coherent      : Present if dma operations are coherent

- calxeda,port-phys : phandle-combophy and lane assignment, which maps each

			SATA port to a combophy and a lane within that

			combophy

- calxeda,sgpio-gpio: phandle-gpio bank, bit offset, and default on or off,

			which indicates that the driver supports SGPIO

			indicator lights using the indicated GPIOs

- calxeda,led-order : a u32 array that map port numbers to offsets within the

			SGPIO bitstream.



Example:

        sata@ffe08000 {

		compatible = "calxeda,hb-ahci";

		reg = <0xffe08000 0x1000>;

		interrupts = <115>;

		dma-coherent;

		calxeda,port-phys = <&combophy5 0 &combophy0 0 &combophy0 1

					&combophy0 2 &combophy0 3>;

		calxeda,sgpio-gpio =<&gpioh 5 1 &gpioh 6 1 &gpioh 7 1>;

		calxeda,led-order = <4 0 1 2 3>;

        };
