The device_state module is used for debouncing GPIO inputs to
determine device sstate. It was overkill for managing the CCD cable
(RDD) attach/detach state, and split that handling between 3 files
(board.c, rdd.c, device_state.c). Move all of that logic into rdd.c
so it's easier to maintain.
BUG=none
BRANCH=cr50
TEST=manual
plug in CCD cable (or ground DIOM1)
ccd command reports cable connected and AP UART TX+RX
unplug CCD cable (or un-ground DIOM1)
ccd command reports cable disconnected and AP UART disabled
