nrf51: Add definitions for GPIOTE, the GPIO Tasks and Events.
Updated to use parameters for GPIOTE_OUT, GPIOTE_IN, and GPIOTE_CONFIG
Updated with NRF51_GPIOTE_IN_COUNT to remove the magic number.
BUG=chrome-os-partner:34477
BRANCH=none
TEST=Configured IN[] events and PORT events and checked that they triggered
events and wrote to the console.
