Merge branch 'sh_eth'

Ben Hutchings says:

====================
Fixes for sh_eth #2

I'm continuing review and testing of Ethernet support on the R-Car H2
chip.  This series fixes more of the issues I've found, but it won't be
the last set.

These are not tested on any of the other supported chips.
