ASoC: simple-card-utils: add asoc_simple_card_of_parse_tdm()

Browse source 
Current simple card drivers are using asoc_simple_dai's tx_slot_mask,
rx_slot_mask, slots, slot_width directly to parse TDM.
Encapsulation is one of simple card util's purpose.
Let's add asoc_simple_card_of_parse_tdm for it.
