ASoC: fsl_sai: Constrain sample rates from audio PLLs only in master mode

If SAI works in master mode it will generate clocks for external codec
from audio PLLs. Thus sample rates should be constrained according to
audio PLL clocks. While SAI works in slave mode which means clocks are
generated externally then constraints are independent of audio PLLs.
