[PATCH v2 1/3] ASoC: binding: add tdm-slot.txt

[Xiubo Li <Li.Xiubo@freescale.com>]

TDM slot:

This specifies audio DAI's TDM slot.

Each entry is has four non-negative integer values in DT:
       <tx_mask, rx_mask, slots, slot_width>

For instance:
       simple-slot-info = <0xffffffc 0xffffffc 2 0>;

And this will be parsed into the following format:
       struct soc_slot_info {
              unsigned int tx_mask;
              unsigned int rx_mask;
              int slots;
              int slot_width;
       };
