crossystem: add GpioChipset sturcture for x86
Up until recently the x86 systems had a single contiguous
set of gpio numbers exported through /sys/class/gpio
as /sys/class/gpiochip<X> values. BayTrail systems have
3 sets of gpio numbers. Therefore, there needs to be a
translation/look-up function based on chipset. The existing
chipsets have a 1:1 mapping, but this patch lays the ground-
work for chipset-specific translation.
