Additional changes:
- Add reg-names list, ahci and sata-ecc
- Add fsl,ls1028a-ahci and fsl,lx2060a-ahci

-Binding for Freescale QorIQ AHCI SATA Controller
-
-Required properties:
-  - reg: Physical base address and size of the controller's register area.
-  - compatible: Compatibility string. Must be 'fsl,<chip>-ahci', where
-    chip could be ls1021a, ls1043a, ls1046a, ls1088a, ls2080a etc.
-  - clocks: Input clock specifier. Refer to common clock bindings.
-  - interrupts: Interrupt specifier. Refer to interrupt binding.
-
-Optional properties:
-  - dma-coherent: Enable AHCI coherent DMA operation.
-  - reg-names: register area names when there are more than 1 register area.
-
-Examples:
-       sata@3200000 {
-               compatible = "fsl,ls1021a-ahci";
-               reg = <0x0 0x3200000 0x0 0x10000>;
-               interrupts = <GIC_SPI 101 IRQ_TYPE_LEVEL_HIGH>;
-               clocks = <&platform_clk 1>;
-               dma-coherent;
-       };
