When we want to support more sample rate, for example 12kHz/24kHz we need update the process_option table, if we want to support more sample rate next time, the table need to be updated again. which is not flexible.
We got a function fsl_asrc_sel_proc to replace the table, which can give the pre-processing and post-processing options according to the sample rate.

- Unsupport cases: Tsout > 8.125 * Tsin, Tsout > 16.125 * Tsin
Since we have a ratio validation somewhere else, it's okay to drop this line -- it may confuse people since the function no longer checks these unsupported cases.
+static int fsl_asrc_sel_proc(int inrate, int outrate,
I think "void" type should be just fine as we made sure there is no unsupported cases running in this function.
