Drop 'xusb_'.

The properties are constant and we use the name to get the power domain.

tegra->genpd_dev_host = dev_pm_domain_attach_by_name(dev, "xusb_host");

tegra->genpd_dev_ss = dev_pm_domain_attach_by_name(dev, "xusb_ss");

we might not be able to drop the xusb_

These are new bindings, so why do say they are "constant"? New bindings
means you did not use them. If you used them before bindings... what can
we say? Don't?

Not exactly. However, what we should do here is convert the legacy binding doc [0] and replace with this one. But yes we are stuck with the 'xusb_host' naming.
