Subject: [PATCH v2] sh_eth: add R8A7791 support

Add support for yet another ARM member of the R-Car family, R-Car M2, also known
as R8A7791 -- it will share the code and data with previously added R8A7790.
Despite the Ether devices in these SoCs are indistinguishable at least from the
driver's point of view, we do introduce a new platform device ID "r8a7791-ether"
unlike the wildcard ID used for R8A7778/9 SoCs, due to newly established policy
for the Renesas SoCs.

This patch is atop of DaveM's 'net-next.git' repo.

Changes in version 2:
- added a new platform device ID for R8A7791 instead of changing the existing ID
  for R8A7790 to a R8A779x wildcard ID.
