HID: ft260: wake up device from power saving mode
The FT260 can enter a power saving mode after being idle for longer
than 5 seconds.
When being woken up from power saving mode by an I2C write request,
a possible NACK is not correctly reported by the controller. As a
workaround, the driver will issue an I2C status report two times in
ft260_xfer_status() after the chip has been idle for more than 5s.
