net: stmmac: enable MTL ECC Error Address Status Over-ride by default

Turn on the MEEAO field of MTL_ECC_Control_Register by default.

As the MTL ECC Error Address Status Over-ride(MEEAO) is set by default,
the following error address fields will hold the last valid address
where the error is detected.
