[PATCH v2] ASoC: dt-bindings: imx-card: Add dsp_a DAI format

[Chancel Liu]

The imx-card machine driver originally supported only codecs operating
in i2s or dsp_b formats. This machine driver can support CS42448 codec
and this codec typically uses dsp_a for its TDM interface. Therefore,
dsp_a format support is required for describing such sound cards in DT.

Update DT bindings to include "dsp_a" in the list of supported DAI
formats.
