[HVM] Prevent usb driver crashes in Windows

Use atomic updates to read/write usb controller data.
This can be done because:
    a) word copies on x86 are atomic
    b) The USB spec requires word alignment

This will need to be enhanced once USB 1.2 is supported.

Update to copy 'longword'-sized atoms.
