net: stmmac: Add support for DWMAC5 and implement Safety Features

This adds initial suport for DWMAC5 and implements the Automotive Safety
Package which is available from core version 5.10.

The Automotive Safety Pacakge (also called Safety Features) offers us
with error protection in the core by implementing ECC Protection in
memories, on-chip data path parity protection, FSM parity and timeout
protection and Application/CSR interface timeout protection.

In case of an uncorrectable error we call stmmac_global_err() and
reconfigure the whole core.
