This commit switches the Orion5x Device Tree files to use the DT
representation and probing for the mvebu-mbus driver. The changes are
mainly:
* Re-organize the DT to follow the same organization as the one used
on Armada 370/XP, which is needed for mvebu-mbus to work: a
top-level soc { ... } node, which corresponds to the MBus bus, and
a sub-node internal-regs { ... } for all peripherals whose register
sit only in the "Internal Register Window". This change re-indents
by one level the definition of all nodes in the Device Tree, which
explains the large change.
* Use custom functions orion5x_dt_init_early() and
orion5x_dt_init_time() instead of orion5x_init_early() and
orion5x_timer_init() as we now want the MBus driver to be probed
from the Device Tree. We still use the old-style timer
initialization, but that will be changed in a followup commit.

This commit switches the Orion5x Device Tree files to use C
preprocessor based includes, as it will allow us to use definitions
from header files in future commits.

The interrupt controller node was located outside of the ocp@f1000000
node, which doesn't make much sense: like any other device, the
interrupt controller has registers located in the "Internal Registers
Window", so it is much more logical to have it under the ocp@f1000000
node.
It is even more important as we are going to move Orion5x to use the
Device Tree binding of the mvebu-mbus driver.

- Add new documents with guidelines for DT binding stability and review
process. This is one of the outcomes of Kernel Summit DT discussions.
- Remove a bunch of device_type usage which is only for OF and
deprecated with FDT.
- Fix a long standing issue with compatible string match ordering.
- Various minor binding documentation updates.

device_type is deprecated and the kernel doesn't require it in most
cases. The only exceptions for flat tree users are the "gianfar",
"ucc_geth" and "ibm,emac" bindings, and arguably that requirement could
be relaxed for ucc_geth and ibm,emac (that is a task for separate
patches though).
This patch removes references to device_type="network" from the binding
documentation where possible and removes the properties from ARM and
microblaze dts files. This patch does not modify the powerpc .dts files
since there are a much larger number of them affected and I think the
ucc_geth, ibm,emac and gianfar users should be addressed before clearing
out the references to reduce the chance of breakage.

Future irqchip driver for Orion SoCs has a modified reg layout starting
from CAUSE register. The former DT irq driver stub just used what the
non-DT driver wants. Currently, orion5x is not ready for irqchip driver
because of legacy timer and missing DT clk provider. To ease future
conversion and just because orion-intc binding documentation already
reflects new reg layout, we convert orion5x DT now.

Device-tree updates for 3.10. The bulk of the churn in this branch is due
to i.MX moving from C-defined pin control over to device tree, which is
a one-time conversion that will allow greater flexibility down the road.
Besides that, there's PCI-e bindings for Marvell mvebu platforms and a
handful of cleanups to tegra due to the new include file functionality
of the device tree compiler.

The crypto functionality in the orion5x dtsi uses the Ethernet IRQ and

The IRQ for the crypto should be 28, and not 22, and that is what this

DT_MACHINE structure to support boards converted to DT in the future.
So far, the Device Tree contains the interrupt controller, the GPIO
bank, the UART controllers, the SPI controller, the watchdog, the SATA
controller, the I2C controller and the cryptographic engine.
