UDC updates for AT91 series processors:
- Get ready for at91sam926x processors (ARMv5tej not ARMv4t)
- Suspend/resume support now behaves properly
- In "standby" mode, UDC can be a source of system wakeup events
(host resume, device connect/disconnect, etc)
- Fix IRQ storming issues, seemingly related to clock disabling
changes that went in a while back
And minor cleanups, especially whitespace.

AT91: the two USB drivers (OHCI, UDC) got out of sync with various
usbcore and driver model PM updates; fix.
Also minor fixes to ohci: whitespace/style, MODULE_ALIAS so coldplug works
using /sys/.../modalias, and turn off _both_ clocks during suspend.

This adds support for the USB peripheral controller on AT91
(rm9200, eventually also sam9261 or uClinux) platforms.
More SOC support for Linux-USB ... an uncomplicated pure PIO driver.
It'd be worth using this as a model, if you're starting a driver
for some other peripheral controller.
