[PATCH] USB: PM support for zd1201

This patch enables power management (suspend, resume) support for zd1201.
It fixes problems after wakeup for me, but these problems did not appear
everytime without this patch.  it's a bit empirical, based on what the
usbnet does, so maybe not correct...  Maybe someone can give it a look
before it's applied.
