usb: add ehci adapter
This patch finally merges the EHCI host adapter aka USB 2.0 support.
Based on the ehci bits collected @ git://git.kiszka.org/qemu.git ehci
EHCI has a long out-of-tree history. Project was started by Mark
Burkley, with contributions by Niels de Vos. David S. Ahern continued
working on it. Kevin Wolf, Jan Kiszka and Vincent Palatin contributed
bugfixes.
/me (Gerd Hoffmann) picked it up where it left off, prepared the code
for merge, fixed a few bugs and added basic user docs.
