Add clock identifiers for the I2S MCLK output to IO gate clocks on
RK3588. These clocks control whether the internal I2S MCLK signals
reach the external IO pins through gates in the SYS_GRF register
(SOC_CON6, offset 0x318).

The following gate clocks are defined:
  - I2S0_8CH_MCLKOUT_TO_IO (bit 0)
  - I2S1_8CH_MCLKOUT_TO_IO (bit 1)
  - I2S2_2CH_MCLKOUT_TO_IO (bit 2)
  - I2S3_2CH_MCLKOUT_TO_IO (bit 7)

These are needed by board DTS files that connect external audio codecs
to I2S interfaces, where the codec requires MCLK from the SoC.

We see that in the diff. No need to repeat, because it makes your small
change unnecessarily big. There is no benefit in writing tons of obvious text.
