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. [2][3]
