cr50: remove unused detect_off interrupt
The interrupts to detect when the falling edge on the UART signals are
currently disabled and never reenabled. Power off is detected by polling
and not through interrupts. This change removes all of those falling
edge interrupts.
BUG=none
BRANCH=none
TEST=cr50 can detect when the EC, AP, and Servo are off or on
