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.

the panel definition.

Currently the Tamonten DTS define a fixed regulator for the 5V supply.
However this regulator is in fact on the base board. Fix this by
properly defining the regulators found on the base boards.

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 the Tegra20 CAR binding header (tegra20-car.h) to replace magic
numbers in the device tree. For example,

-               clocks = <&tegra_car 28>;
+               clocks = <&tegra_car CLK_HOST1X>;

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.

We should be defining the PWM nodes with status as "disabled" in the
chip-specific dtsi file, since we don't know whether specific boards
will use the PWM or not. This patch fixes the PWM node status for
Tegra20 and Tegra30.

Also fixed the one user of PWM, which is the Tegra20 medcom-wide board,
so that PWM is set to "okay" in the board-specific dts file.
