ASoC: dt-bindings: sound: spacemit,k1-i2s: allow 6 clocks for K3 i2s1

Browse Source 
The K3 I2S controllers normally use the published 7-clock layout:

  sysclk, bclk, bus, func, sysclk_div, c_sysclk, c_bclk

However, K3 i2s1 has no dedicated sysclk divider and therefore uses a
6-clock layout:

  sysclk, bclk, bus, func, c_sysclk, c_bclk

Describe the 4-clock K1 and both K3 layouts as separate tuples. Lower
the K3 minimum from 7 to 6 clocks while preserving the existing
7-clock ordering.
