ASoC: fsl_sai: Add registers definition for multiple datalines 

SAI IP supports up to 8 data lines. The configuration of
supported number of data lines is decided at SoC integration
time.

This patch adds definitions for all related data TX/RX registers:
	* TDR0..7, Transmit data register
	* TFR0..7, Transmit FIFO register
	* RDR0..7, Receive data register
	* RFR0..7, Receive FIFO register
