====================
ravb: Support 1Gbps on R-Car H3 ES1.1+ and R-Car M3-W

this series adds support for gigabit communication to the Renesas
EthernetAVB controller when used in conjunction with R-Car Gen3 H3
ES1.1+ and M3-W SoCs.  Gigabit is already supported with R-Car Gen 2
SoCs.

The patch from Geert was previously posted for inclusion in v4.10 and
acked by Dave for that purpose. It was, however, not accepted by the
ARM SoC maintainers.

The path from Mizuguchi-san is to address timing problems observed
with gigabit transfers. I would like it considered although my own
testing on M3-W did not show any timing problems.

Changes since v1:
* Address various feedback for "APSR" patch as noted in its changelog
