The USB controllers on Tegra124 are backwards-compatible with those
found on Tegra30.

These properties still all need the Tegra124 value in there too, just in
case there's a need to differentiate in the future. I can fix that up
when applying.

I've added those in v3 that I just sent out. I added Tegra124 values for
both the USB EHCI controllers as well as the PHY nodes.
