dpaa2-eth: Initialize mutex used in one step timestamping path

Browse source

1588 Single Step Timestamping code path uses a mutex to
enforce atomicity for two events:
- update of ptp single step register
- transmit ptp event packet

Before this patch the mutex was not initialized. This
caused unexpected crashes in the Tx function.

Fixes: c55211892f ("dpaa2-eth: support PTP Sync packet one-step timestamping")
