ARM: dts: rockchip: Add i2s nodes for RK3128

Browse Source 
RK3128 SoCs have two i2s controllers. i2s_8ch has 8 tx and 2 rx channels
and is internally hard-wired to the hdmi-controller respectivly the SoC's
analog codec. i2s_2ch has 2 tx and 2 rx channels and can also be used
externally as it's pins are exposed though pinctrl.
