RZ/G2L need 4byte address alignment like R-Car Gen2 and it has
tx_counters like R-Car Gen3. This patch enable these features for
RZ/G2L.

   Mhm, I don't see a connection between those 2 (other than they're
both for RX). And anyway, this prolly should be a part of the previous

patch...

There was a discussion to make smaller patches. If there is no objection,
on the next revision I will add this as part of previous patch.

Thanks, As discussed, I have merged this with previous patch, as it is trivial change.

Regards,
Biju
