net: altera-tse: Warn on bad revision at probe time

Instead of reading the core revision at probe time, and print a warning
for an unexecpected version at .ndo_open() time, let's print that
warning directly in .probe().

This allows getting rid of the "revision" private field, and also
prevent a potential race between reading the revision in .probe() after
netdev registration, and accessing that revision in .ndo_open().

By printing the warning after register_netdev(), we are sure that we
have a netdev name, and that we try to print the revision after having
read it from the internal registers.
