On sun4i-a10, when GPIOs are configured as external interrupt the value for them in the data register does not seem to get updated, so set their mux to input (and restore afterwards) when reading the pin. Missed edges seem to be buffered, so this does not introduce a race condition. I've also tested this on sun5i-a13 and sun7i-a20 and those do not seem to be affected, the input value representation in the data register does seem to correctly get updated to the actual pin value while in irq mode there.
