sb/ich7: Use common/gpio.h to set up GPIOs
This is more consistent with newer Intel targets.
This a static struct so it is initialized to 0 by default.
To make it more readable:
* only setting to GPIO mode is made explicit;
* only pins in GPIO mode are either set to input or output since this
is ignored in native mode;
* only output pins are set high or low, since this is read-only on
input;
* blink is only operational on output pins, non-blink is not set
explicitly;
* invert is only operational on input pins, non-invert is not set
explicitly.
