GPLv2-only devicetrees make reuse difficult for software components
licensed under a different license.

The consensus is that a GPL/X11 dual-license should allow all necessary
uses, so relicense the vf*colibri* files to this combination.

Add Colibri standard pinmux for FlexCAN controller instances. CAN
is not a standard Colibri feature, but the datasheet predefines
pins which provide CAN (compatible across some modules). Hence,
add the pinmux on module level.

This commit includes a minor nomenclature fixup for boards based on the
Freescale VF610 SoC and which make use of the alternate "RMII1_RXD1"
functionality for pin PTC12.  This brings the macro name in-line with
both the datasheet and other similar macros.

On Vybrid, all peripherals are numbered starting with zero,

This adds more generic base device trees for Vybrid SoCs. There
are three series of Vybrid SoC commonly available:
- VF3xx series: single core, Cortex-A5 without external memory
- VF5xx series: single core, Cortex-A5
- VF6xx series: dual core, Cortex-A5/Cortex-M4

The second digit represents the presents of a L2 cache (VFx1x).

The VF3xx series are not suitable for Linux especially since the
internal memory is quite small (1.5MiB).

The VF500 is essentially the base SoC, with only one core and
without L1 cache. The VF610 is a superset of the VF500, hence
vf500.dtsi is then included and enhanced by vf610.dtsi. There is
no board using VF510 or VF600 currently, but, if needed, they can
be added easily.

The Linux kernel can also run on the Cortex-M4 CPU of Vybrid
using !MMU support. This patchset creates a device tree structure
which allows to share peripherals nodes for a VF6xx Cortex-M4
device tree too. The two CPU types have different views of the
system: Foremost they are using different interrupt controllers,
but also the memory map is slightly different. The base device
tree vfxxx.dtsi allows to create SoC and board level device trees
supporting the Cortex-M4 while reusing the shared peripherals
nodes.

The Colibri standard defines four pins as PWM outputs, two of them (PWM
A and C) are routed to FTM instance 0 and the other two (PWM B and D)
are routed to FTM instance 1. Hence enable both FTM instances for the
Colibri module and mux the four pins accordingly.

Add USB support for Colibri VF61 modules. The Colibri standard pinout
defines a pin for USB over-current. However, due to lack of pinmux
options, the USB hosts over-current protection signal of the Colibri
standard could not be connected to the PHY's over-current protection.
Hence we need to disable the over-current functionality of the USB
controller.

The Colibri VF61 is a module which needs a carrier board to actually
run. Different carrier board have different hardware support, hence
we should reflect this in the device tree files. This patch adds the
Colibri Evaluation Board, which supports almost all peripherals
defined in the Colibri standard.

Also align the compatible naming, file splitting and file naming with
the scheme which was choosen for the Tegra based modules.

Currently, all pinctrl setting nodes are defined in <soc>.dtsi, so that
boards that share the same pinctrl setting do not have to define it time
and time again in <board>.dts.  However, along with the devices and use
cases being added continuously, the pinctrl setting nodes under iomuxc
becomes more than expected.  This bloats device tree blob for particular
board unnecessarily since only a small subset of those pinctrl setting
nodes will be used by the board.  It impacts not only the DTB file size
but also the run-time device tree lookup efficiency.

The patch moves all the pinctrl data into individual boards as needed.
With the changes, the pinctrl setting nodes becomes local to particular
board, and it makes no sense to continue numbering the setting for
given peripheral.  Thus, all the pinctrl phandler name gets updated to
have only peripheral name in there.
