[PATCH 17/25] dt-bindings: spi: rockchip: Add RV1106 compatible

The RV1106 SPI controller is compatible with the one found on RK3066,
so add the "rockchip,rv1106-spi" compatible to the list of variants
that fall back to "rockchip,rk3066-spi".

The RV1106 SPI controller also has an additional external slave clock
input (sclk_in), so extend clocks/clock-names with a third,
description/const entry for it.
