smsc75xx: add support for USB dynamic autosuspend
This patch adds support for USB dynamic autosuspend to the smsc75xx driver. This saves virtually no power in the USB device but enables power savings in upstream hosts and the host CPU. Note currently Linux doesn't automatically enable this functionality by default for devices so to test this: echo auto > /sys/bus/usb/devices/2-1.2/power/control where 2-1.2 is the USB bus address of the LAN7500.
