Christian Lamparter f7c1d9c8a5 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.
