ASoC: fsl-utils: Add fsl_asoc_xlate_tdm_slot_mask() support.
This patch add fsl_asoc_xlate_tdm_slot_mask() support for utils.
For the some spcified DAI driver, this will be used to generate the
TDM slot TX/RX mask. And the TX/RX mask will use a 0 bit for an active
slot as default, and the default active bits are at the LSB of
the masks.
