ar71xx_gpio.c touches SPI_CS1 and 2?

[Stefan Bethke]

I was looking into why I can't manipulate the USB led on my TL-WR1043ND, and came across the SPI chip selects, which share GPIO 0 and 1, respectively.  The USB led is hooked up to GPIO 1.

sys/mips/atheros/ar71xx_gpio.c:ar71xx_gpio_attach(device_t dev) enables both chip selects, and detach disables them again.

Two points:

- how can we express different uses for those two pins on a per-board config?

- disabling the function is not correct for the gpio driver, I would think.  If you load and unload it as a module, I expect losing access to the flash.
