Add a device node for the MIPI calibration block on Tegra114. There is
no need to disable it by default because it only enables the clock while
performing calibration and therefore shouldn't be consuming any power
when unused.

Signed-off-by: NStephen Warren <swarren@nvidia.com>

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!
Signed-off-by: NStephen Warren <swarren@nvidia.com>

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.

This patch depends on "ASoC: tegra: use reset framework" to compile,
which is ack'd and slated to go through a (large) topic branch in the
Tegra tree. So, we can either:

a) Merge that Tegra topic branch into the ASoC tree, then apply this.
   Note that I haven't created the topic branch yet, since I'm still
   waiting for DMA dependencies to be applied.

b) Apply this change to the Tegra tree too. This change isn't directly
   related to the changes in the Tegra tree; it just makes use of the new
   reset controller feature that's introduced there.

The "pcie_xclk" clock is not actually a clock at all, but rather a reset
domain. Now that the custom Tegra module reset API has been removed, we
can remove the definition of any "clocks" that existed solely to support
it.
