cc2538: gpio: Add macros to get interrupt status

Browse source 
Introduce new useful GPIO macros to:
 - get the raw interrupt status of a port,
 - get the masked interrupt status of a port,
 - get the power-up interrupt status of a port.

These macros are cleaner and less error-prone than raw register access
code copied all over the place.
