Werner Almesberger 370cd320ef atusb/fw: new request ATUSB_GPIO for direct GPIO access
reset_rf now resets all GPIOs to their default state. This way, we
can easily recover from an incomplete or incorrect use of ATUSB_GPIO.

- atusb.c (main), board.c (reset_rf): moved call to spi_init into
  reset_rf
- board.c (reset_rf, board_init): moved GPIO setup to reset_rf
- board.c (reset_rf): set GPIOs to reset defaults
- board.h (gpio), board.c: read/modify/write all settings of GPIO
  ports
- include/atusb/ep0.h (enum atspi_requests): added new request
  ATUSB_GPIO
- ep0.c (my_setup): ATUSB_GPIO reads/reconfigures a GPIO port
