MLK-22161: fsl_easrc: Remove float point format support

The input audio float data range is normalized to (-1, 1), but
the hardware will drop to fractional part if output format
is integer format, so the output is all zero, which does not flow
the normal audio case, that to shift the output to Q15/Q31.
