arm64: dts: rockchip: add SPDIF node for rk3399-rockpro64
This patch adds 'disabled' SPDIF sound node and related settings
for rk3399-rockpro64.
There are 2 reasons:
- All RK3399 dma-bus channels have been already used by I2S0/1/2
- RockPro64 does not have SPDIF optical nor coaxial connector,
just have 3pins
