SAM3/4: Fix GPIO pull-up/down code.
...
Enabling the pull-down resistor while the pull-up resistor is still enabled
is not possible. In this case, the write of PIO_PPDER for the relevant I/O
line is discarded. Likewise, enabling the pull-up resistor while the
pull-down resistor is still enabled is not possible. In this case, the
write of PIO_PUER for the relevant I/O line is discarded.

SAM3/4 GPIO: Enable peripheral clock for GPIO port when GPIO is configured as input.
...
The value of a GPIO input is only sampled when the peripheral clock for
the port controller the GPIO resides in is enabled. Therefore we need
to enable the clock even when polling a GPIO.
