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.

Cadhu have multiple power rails which are controlled by
GPIOs. Add support of these power rail control through
fixed regulators. Add entry for all fixed regulators for
cardhu-a02 and a04.
The details are taken from downstream kernel.

Some points on this change are:

* Add the tps65910-LDO5 entry and make it always ON
 to supply power to SDMMC. Once the sd driver support
 regulator handling, this flag will be remove.

* Dropping registration of rail vdd_sdmmc1 as the gpio
  is used by sdhci power-gpio. This need to fix in
  sdhci driver and then need to add the registration
  mechanism. Just removing power-gpio and adding fixed
  regulator with this gpio is causing the sd  access to
  fail because first probe call of this regulator fails
  due to non-available of parent and so it calls
  gpio_free() which disable the pins in gpio mode make
  pin output to LOW causes power to OFF. In probe retry,
  it got success and it powered-on but it again need to
  do again numeration of card here.

Cardhu A01 and A03 are not supported. Cardhu A02 will have
different sets of GPIOs for fixed regulator compare to
cardhu A04. The Cardhu A05, A06, A07 are compatibe with A04.
Based on cardhu version, the related dts file need to be chosen
like for cardhu A02, use tegra30-cardhu-a02.dts, cardhu A04 and
more, use tegra30-cardhu-a04.dts.

Most ARM ${board}.dts files are already named ${soc}-${board}.dts. This
change modifies the Tegra board files to be named the same way for
consistency.

Once a related change is made in U-Boot, this will cause both U-Boot and
the kernel to use the same names for the .dts files and SoC identifiers,
thus allowing U-Boot's recently added "soc" and "board" environment
variables to be used to construct the name of Tegra .dtb files, and hence
allow board-generic U-Boot bootcmd scripts to be written.

* Second, any nodes with a reg property, in numerical order.
* Third, any nodes without a reg property, in alphabetical order of node
  name.

The second sorting rule at least will probably help if/when we need to
explicitly insert nodes for the various busses in Tegra; that will just
