[d-kernel] [PATCH 2/7] arm64: dts: rockchip: Add SPDIF nodes to RK3588(s) device trees

[Daniil Gnusarev <gnusarevda@basealt.ru>]

From: Alexey Charkov <alchark@gmail.com>

RK3588s has four SPDIF transmitters, and the full RK3588 has six.
They are software compatible to RK3568 ones. Add respective nodes
to .dtsi files.

Adapted from vendor sources at [1] and [2], respectively
