The libahci now allows to use multiple PHYs and to represent each port
as a sub-node. Add these bindings to the documentation.

Add the documentation for the electrical properties for the iMX SATA
controller.  There are many values for these, and listing them would
be error prone.  Refer readers to the device documentation and driver
source code for these details.

The Freescale i.MX SATA controller mostly conforms to the AHCI
interface, but there are some special extensions at integration level
like clocks settings and hardware parameters.

Let's create a separate bindings doc for imx sata controller, so that
more imx specific properties can be added later without messing up the
generic ahci-platform bindings.

The hip04 SoC of hisilicon has an AHCI compliant SATA controller,
and it is compliant with the ahci 1.3 and sata 3.0 specification.

There is a wrong bit in HOST_CAP of hip04 sata controller, which
enable unsupported feature of FBS, use AHCI_HFLAG_NO_FBS hflag to
disable it.

The Marvell Armada 380 SoC includes two AHCI compatible
interfaces. However, like all DMA-capable Marvell interface, they
require special handling to configure MBus windows. Therefore, this
commit adds a new ahci_mvebu driver, which relies on the
libahci_platform.c code recently introduced.

The ahci-platform.txt Device Tree binding documentation is gaining a
growing number of compatible strings, and it will gain one more with
the addition of the Marvell Armada 380 AHCI support. It is therefore
time to reformat this list into a proper bullet list, and more
importantly order it alphabetically;
