[PATCH 30/47] ARM: dts: r8a7793: Reference both DMA controllers in IIC nodes

[Simon Horman]

From: Niklas Söderlund <niklas.soderlund+renesas at ragnatech.se>

R-Car Gen2 have two DMA controllers, which are equivalent. Add
references to both dmac0 and dmac1 so the driver can fallback to the
later if the first one is unavailable.
