ASoC: mxs-saif: add record function
1. add different clkmux mode handling SAIF can use two instances to implement full duplex (playback & recording) and record saif may work on EXTMASTER mode which is using other saif's BITCLK&LRCLK. The clkmux mode could be set in pdata->init() in mach-specific code. For generic saif driver, it only needs to know who is his master and the master id is also provided in mach-specific code. 2. support playback and capture simutaneously however the sample rates can not be different due to hw limitation.
