pn80t gpio: wire up the gpio toggle

This change connects the interface targeted
APDU:
    0xff 0xe0 0x00 0x00
to the nq-nci platform to allow the inBootloader
gpio to be toggled (cleared).

Test: works with the new kernel
      echo -e 'ffe00000 9000' | strace -e ioctl ese-replay nq-nci # shows ioctl
      applet or kernel state not toggling.
