[Sergei Shtylyov]

Add the (previously omitted) EtherAVB pin data to the Eagle board's
device tree.

The patch is against the 'renesas-devel-20180314-v4.16-rc5' tag of Simon's
'renesas.git repo. It depends on the R8A77970 PFC driver patch adding EtherAVB
pin groups (posted yesterday) in order to work properly...

Changes in version 2:
- updated the pin groups according to the recent PFC driver patch;
- updated due to  the patch reordering.
