cc3200: Rename GPIO module to Pin.
This change helps making the cc3200 port API a bit closer to stmhal. The ramaining differences are due to the specific hardware details of each chip. One feature that has been deliberately disabled is the possibility to add custom names and custom pin mappings. Those features are nice and convenient, but in this port, code size is a major concern.pull/1068/merge
