apm821xx: detect sd-card media changes for the WNDR4700
The insertion or removal of the sd-card cannot be detected by the hardware itself. This is by design. To workaround this, for the WNDR4700 unload/load the dwc2 module in case the the special SD CARD GPIO line is low/high. Signed-off-by: Christian Lamparter <chunkeey@gmail.com>
