Enhance cros_write_firmware to report success explicitly
When cros_write_firmware utility is invoked to program an ARM system's
firmware, the verification success is not reported on the console (the
failures are reported implicitly when a CRC mismatch is
detected). After this change both success and failure are reported
explicitly, which allows scripting tools to look for known patterns.

TEST=manual
. run the following command:
$ cros_write_firmware -b daisy -w usb -d exynos5250-snow -F spi \
-i /build/daisy/firmware/image-daisy.bin -V

. corrupted the SPI Flash contents on Snow, modified
write_firmware.py to update only part of the image and reran the
above command.
