phy: mscc: Fix parsing of unicast frames

According to the 1588 standard, it is possible to use both unicast and
multicast frames to send the PTP information. It was noticed that if the
frames were unicast they were not processed by the analyzer meaning that
they were not timestamped. Therefore fix this to match also these
unicast frames.
