Add support for the first two members of the Renesas RZ/G family, RZ/G1M/E
(also known as  R8A7743/5). The Ether core is the same as in the R-Car gen2
SoCs, so will share the code/data with them...

The patch is against the DaveM's 'net-next.git' repo.

Re-sending with the DT maintainers/list included this time...

Surely "R8A7740" is covered by "R8A774x"? :-)
However, the "x" is not a real wildcard (also for '7x and '9x), as the driver
doesn't support all possible values of "x".

Apart from that:

    It should be, yes -- but 7740 has completely different Ether core than the 
RZ/G family. I can fix this if you want...

    Well, I think for 779x it does, provided that the Ether core exists at all.
For 777x it doesn't support the SH flavour of 7778 indeed but it's not 
supported by the kernel at all...

   Thank you. :-)
