ath25: fix ethernet supported link modes for ar2313

Rework ethernet supported link modes to linkmode bitmask.

This is needed to suppress compilation errors:

   drivers/net/ethernet/atheros/ar231x/ar231x.c:1153:20: ...
     error: assignment to expression with array type
     phydev->supported &= (SUPPORTED_10baseT_Half
                       ^~
