I think this should be merged with previous patch. Also, we need to
check whether tx-fifo-resize is needed with ES2 or not ;-)

yeah. ES2 works without tx-fifo-resize.

Great, I guess we can deprecate that attribute. Can you check if ES2
still works with:

starting on 1.94a (IIRC) core was supposed to control PHYs directly and
since there's nobody in linux mainline using any version prior to 1.94a,
we could drop that too.

Will check that in a while.
