nocturne_fp/board: Define CONFIG_PANIC_STRIP_GPR in config
Fingerprint MCU is processing sensitive data (fingerprints, keys).
Defining this option will prevent leaking the data in General Purpose
Registers.
BUG=b:193408648
BRANCH=none
TEST=`make BOARD=dartmonkey`. Flash image on icetower.
Trigger panic using 'crash' command. After reboot, use 'panicinfo'
to check what was saved. When CPU exception occurred registers
R0-R12 should be set to 0. In case of software panic, R4 and R5 can
contain panic reason and additional information.
