Sam Hurst	cdcc09096a	common: Substitute modified CRC8 with CRC-5-USB ... The modified CRC8 implementation didn't detect some errors. For example, using the modified CRC8: CC5QQLALU and DC5QQLALU calculates to the same value. BUG=b:37952913 BRANCH=none TEST=make buildall Used online CRC-5-USB calculator to test several values against this implementation.
