ARM: dts: r9a06g032-rzn1d400-db: Enable CAN1
The CN10/CN11 on RZ/N1-EB board are headers to add jumpers to select which
CAN interface to route to the real CAN connector J16.
For a normal use case either we need to wire CAN1 or CAN2, but not both.
This patch enables CAN1 and disables CAN2 by default assuming CN10/CN11
is wired for CAN1.
