I think at the very least you should add a function
"xhci_default_driver(struct hc_driver *driver)" to xhci-plat.c (or
even better to xhci.c and use it for PCI as well) that initializes all
function pointers to the default (internal) symbols, and can then be
overridden afterwards.

Currently all XHCI host drivers (PCI, platform, MVEBU) will be built
into the xhci-hcd module.  I could append the Tegra driver to that
module or introduce a xhci_init_driver() like EHCI does as Julius
suggests.  USB folks, do you have a preference?

As the EHCI maintainer, I naturally approve of Julius's suggestion.
