There are general changes pending to make the /aliases/serial* entries
number the serial ports on the system. On Tegra, so far the ports have
been just numbered dynamically as they are configured so that makes them
change.

To avoid this, add specific aliases per board to keep the old numbers.
This allows us to change the numbering by default on future SoCs while
keeping the numbering on existing boards.

For Tegra DT files, I've been attempting to keep the nodes sorted in
the order:
1) Nodes with reg, in order of reg.
2) Nodes without reg, alphabetically.

This patch fixes a few escapees that I missed:-(

The diffs look larger than they really are, because sometimes when one
node was moved up or down, diff chose to represent this as many other
nodes being moved the other way!

DT node names should include a unit address iff the node has a reg
property. For Tegra DTs at least, we were previously applying a different
rule, namely that node names only needed to include a unit address if it
was required to make the node name unique. Consequently, many unit
addresses are missing. Add them.

Use TEGRA_GPIO() macro to name all GPIOs referenced by GPIO properties,
and some interrupts properties. Use standard GPIO flag defines too.

Replace /include/ (dtc) with #include (C pre-processor) for all Tegra DT
files, so that gcc -E handles the entire include tree, and hence any of
those files can #include some other file e.g. for constant definitions.

This allows future use of #defines and header files in order to define
names for various constants, such as the IDs and flags in GPIO
specifiers. Use of those features will increase the readability of the
device tree files.

This patch updates all Tegra board files so that they contain all the
properties required by the updated USB DT binding. Note that this patch
only adds the new properties and does not yet remove the old properties,
in order to maintain bisectability. The old properties will be removed
once the driver has been updated to assume the new bindings.

This adds the device tree for the Toradex Iris carrier board used
together with a Colibri T20 512MB COM.

The Iris has the following features, in brackets the current status:
- DVI and VGA output through DVI-I connector (DVI-D enabled and tested)
- LVDS output
- 1 USB host port (enabled and tested)
- 1 USB OTG port (enabled)
- 100 MBit Ethernet (enabled and tested)
- 5 UART ports  (2 on 10way headers enabled and tested)
- 1 MicroSD Slot (enabled and tested)
- Audio connectors (enabled, only HP out and Line-in tested)
- i2c RTC
- GPIO connector (enabled, only sparsely tested)
- external i2c bus
- 4 PWM out
- analog in
