arm: juno: enable USB
The Juno board features a standard compliant EHCI/OHCI USB host
controller pair, which we can just enable.
The platform data is taken from the device tree.
This allows to use USB mass storage (the only storage on a Juno r0)
for loading.
At least on my board USB seems a bit flaky, I need two "usb reset"
sequences after the "usb start" to detect an USB hard drive.
