Nico Huber edcde0ba7a libpayload/uhci: Re-write UHCI RH driver w/ generic_hub API 
This is a complete rewrite of the UHCI root-hub driver, based on
the xHCI one. We are doing things by the book as far as possible.
One special case is uhci_rh_reset_port() which does the reset se-
quencing that usually the hardware would do.

This abandons some quirks of the old driver:
* Ports are not disabled/re-enabled for every attachment anymore.
* We solely rely on the Connect Status Change bit to track changes.
* Further status changes are now deferred to the next polling round.

The latter fixes endless loops in combination with commit 7faff543da
(libpayload: usb: Detach unused USB devices).
