ptp: ptp_clockmatrix: update to support 4.8.7 firmware
With 4.8.7 firmware, adjtime can change delta instead of absolute time, which greately increases snap accuracy. PPS alignment doesn't have to be set for every single TOD change. Other minor changes includes: adding more debug logs, increasing snap accuracy for pre 4.8.7 firmware and supporting new tcs2bin format.
