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

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.
