Say yes here to select AT91 PIO GPIO driver. AT91 PIO
controller manages up to 32 fully programmable input/output
lines. Each I/O line may be dedicated as a general-purpose
I/O or be assigned to a function of an embedded peripheral.
The assignment to a function of an embedded peripheral is
the responsibility of AT91 Pinctrl driver. This driver is
responsible for the general-purpose I/O.
