[PATCH 19/25] ARM: dts: rockchip: Add SPI nodes for RV1106

[Vladislav Leonov]

Rockchip RV1106 has two SPI controllers. Add the spi0 and spi1 nodes
together with their aliases, using the m0 pinmux and the DMA channels
of the single DMAC.

Compared to Rockchip BSP kernel add missing SCLK_IN_SPI1 to spi1 node.

Both nodes default to status = "disabled" and are enabled per-board.
