[PATCH 13/25] ARM: dts: rockchip: Add DMAC node for RV1106

[Vladislav Leonov]

Rockchip RV1106 has a single ARM PL330 DMA controller with 8 channels,
shared by the peripherals. Add the dmac node with its 8 event
interrupts plus the abort interrupt.

The controller needs arm,pl330-periph-burst to use burst transfers for
peripheral requests, as on the other Rockchip PL330 platforms.
