From: Xiubo Li <Li.Xiubo@freescale.com>

In the asoc_simple_card_parse_of() will parse the device node's CPU/CODEC
DAI commone fmts, and then in asoc_simple_card_sub_parse_of() will parse
the CPU/CODEC DAI's sub-node fmts, so we can combine the info->daifmt and
info->set.fmt in asoc_simple_card_sub_parse_of() not while just before
_set_fmt().

And this will be more easy to add new functions, such as supporting
_set_tdm_slot(), etc.
