arm64: dts: rockchip: Use "dma-noncoherent" in base RK3588 SoC dtsi
The preferred way to denote hardware with non-coherent DMA is to use the "dma-noncoherent" DT property, at both the GIC redistributor and the GIC ITS levels, [1] instead of relying on the compatibles to handle hardware errata, in this case the Rockchip 3588001 errata. [2] Let's have the preferred way employed in the base Rockchip RK3588 SoC dtsi, which also goes along with adding initial support for the Rockchip RK3582 SoC variant, with its separate compatible.
