MLK-20328-1: ASoC: fsl_sai: map number of pins to dataline masks
The patch enable mapping the number of pins required to play or record
a specific number of channels to a specific dataline mask.
Three consequent elements in "fsl,dataline" and "fsl,dataline,dsd" defines a
particular mapping, for instance for: fsl,dataline = "0 0xff 0xff 2 0x11 0x11"
there are two mappings defined:
default (0 pins) "rx" and "tx" dataline masks: 0 0xff 0xff
2 pins "rx" and "tx" dataline masks: 2 0x11 0x11
In case if property is missing, then default value "0 0x1 0x1" is considered.
