The configuration of the clock depend of the gpio latch. This information
is stored in the gpio block registers. That's why the block is shared

As suggested by Rob Herring, we should:
1/ Use a SoC-specific compatible string in addition to the more generic
one.
2/ The generic compatible string has been changed from
"marvell,mv-xor-v2" to "marvell,xor-v2".
We simply reflect the changes made to the Device Tree bindings to the
relevant Marvell 7K/8K Device Tree files.

This commit adds an initial Device Tree description for the CP110
master that is found in the Armada 7K and 8K SoCs. This initial
description describes:
- the system controller (to provide clocks)
- three PCIe interfaces
- the SATA interface
- the I2C controllers
- the SPI controllers
For the record, the organization of the SoCs is as follows:
- 7020: dual-core AP, one CP110 (master)
- 7040: quad-core AP, one CP110 (master)
- 8020: dual-core AP, two CP110s (master and slave)
- 8040: quad-core AP, two CP110s (master and slave)
For this reason, all of the 7020, 7040, 8020 and 8040 include
armada-cp110-master.dtsi. When support for the second CP110 (slave)
used in 8020 and 8040 will be added, the .dtsi files for those SoCs
will in addition include armada-cp110-slave.dtsi.

This commit slightly improves the description of the SPI flash
connected to the SPI controller of the Armada 7040, by:
- Using the more generic "jedec,spi-nor" compatible string, which
lets the driver auto-detect the exact SPI flash type.
- Removing the silly comment about the Chip Select, since reg = <0>
is explicit enough.
- Switching to the new Device Tree binding to describe flash
partitions.

Following the review from the DT maintainers, the DT binding for the
clocks has changed, and we now use a DFX server node exposing a
syscon, with the clock nodes being subnodes of the DFX server
node. This commit therefore updates the AP806 Device Tree file to use
this new DT binding.

This commit adds the base Device Tree files for the Armada 7K and 8K
SoCs, as well as the Armada 8040 DB board.
The Armada 7020, 7040 (7K family) and 8020, 8040 (8K family) are
composed of:
- An AP806 block that contains the CPU core and a few basic
peripherals. The AP806 is available in dual core configurations
(used in 7020 and 8020) and quad core configurations (used in 8020
and 8040).
- One or two CP110 blocks that contain all the high-speed interfaces
(SATA, PCIe, Ethernet, etc.). The 7K family chips have one CP110,
and the 8K family chips have two CP110, giving them twice the
number of HW interfaces.
In order to represent this from a Device Tree point of view, this
commit creates the following hierarchy:
* armada-ap806.dtsi - definitions common to dual/quad ap806
* armada-ap806-dual.dtsi - description of the two CPUs
* armada-7020.dtsi - description of the 7020 SoC
* armada-8020.dtsi - description of the 8020 SoC
* armada-ap806-quad.dtsi - description of the four CPUs
* armada-7040.dtsi - description of the 7040 SoC
* armada-7040-db.dts - description of the 7040 board
* armada-8040.dtsi - description of the 8040 SoC
The CP110 blocks are not described yet, and will be part of future
patch series.
