hatch_fp: Add RDP (read protection) support to STM32F4
BRANCH=none
BUG=b:125419658
TEST=Remove "-U" flag in STM32MON_READ_FLAGS in flash_fp_mcu_common.sh
flash_fp_mcu -r foo.bin => success
hexdump foo.bin => valid data
ectool --name=cros_fp flashprotect enable
ectool --name=cros_fp reboot_ec
flash_fp_mcu -r foo.bin => fails
Add "-U" flag back to STM32MON_READ_FLAGS in flash_fp_mcu_common.sh
flash_fp_mcu -r foo.bin => success
hexdump foo.bin => all 0xFF
