net: stmmac: Get correct timestamp values from XGMAC
TX Timestamp in XGMAC comes from MAC instead of descriptors. Implement
this in a new callback.
Also, RX Timestamp in XGMAC must be cheked against corruption and we need
a barrier to make sure that descriptor fields are read correctly.
Changes from v2:
- Rework return code check (Jakub)
Changes from v1:
- Rework the get timestamp function (David)
