ASoC: fsl: Rename stream name of SAI DAI driver

If stream names of DAI driver are duplicated there'll be warnings when
machine driver tries to add widgets on a route:

[    8.831335] fsl-asoc-card sound-wm8960: ASoC: sink widget CPU-Playback overwritten
[    8.839917] fsl-asoc-card sound-wm8960: ASoC: source widget CPU-Capture overwritten

Use different stream names to avoid such warnings.
DAI names in AUDMIX are also updated accordingly.

Fixes: 15c9583 ("ASoC: fsl_sai: Add separate DAI for transmitter and receiver")
