[PATCH 3/3] riscv: dts: spacemit: k3: add i2s0-i2s5 nodes

[Troy Mitchell]

Add the six SSPA-based I2S controller nodes for the K3 SoC.

i2s0 and i2s2-i2s5 each have a dedicated per-controller sysclk
divider, so they use the published 7-clock layout (sysclk, bclk, bus,
func, sysclk_div, c_sysclk, c_bclk).

i2s1 uses 6 clocks (sysclk, bclk, bus, func, c_sysclk, c_bclk) because
its sysclk is driven directly by a DDN (ISCCR0) and has no separate
divider stage.
