[PATCH 2/2] ARM: dts: r9a06g032: add EB board device-tree

["Clément Léger" <clement.leger@bootlin.com>]

The EB board (Expansion board) supports both RZ/N1D and RZ-N1S. Since this
configuration targets only the RZ/N1D, it is named r9a06g032-rzn1d400-eb.
It adds support for the 2 additional switch ports (port C and D) that are
available on that board.
