The convention on Tegra is to use "nvidia,<chip>-<ip>" for each IP
block. Additionally, since the XUSB-related blocks on Tegra132 are
identical to Tegra124, these devices on Tegra132 are 'compatible' with
their Tegra124 variants.

For some context, see Paul's comments in commit 193c9d23
("Documentation: DT bindings: add more Tegra chip compatible
strings").
