Bypass the regmap cache when flushing the i2s FIFOs and modify the tables to reflect this.

This patch looks like it's fixing something while the commit log doesn't mention what is being fixed.
Main issue addressed here is that SUN4I_I2S_FIFO_CTRL_REG has two self-clear registers (SUN4I_I2S_FIFO_CTRL_FLUSH_RX and SUN4I_I2S_FIFO_CTRL_FLUSH_TX) and thus it should be marked as volatile.
Best regards, Jernej
Having some context here would be great.
