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

Signed-off-by: Marcus Cooper <redacted>

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.
