MLK-21940-1: ASoC: fsl_asrc: Update mxc_asrc uapi
In order to support the new ASRC in i.MX815, we update the
user api file mxc_asrc.h.
The reason is that the new ASRC support more sample width, and
support endianness, sign, float format, iec958 format setting,
All these type can be expressed by snd_pcm_format_t type.
So we use the in(out)put_format to instead the in(out)put_word_width.
