[PATCH 1/3] arm64: tegra: Add unit-address for CBB on Tegra194

[Thierry Reding <thierry.reding@xxxxxxxxx>]

From: Thierry Reding <treding@xxxxxxxxxx>

The control back-bone (CBB) starts at physical address 0, so give it a
unit-address to comply with standard naming practices checked for by the
device tree compiler.
