ASoC: fsl_micfil: Add decimation filter bypass mode support

Browse source

When decimation filter bypass mode is enabled, PDM data can be
written into FIFO directly without any processing.

The interface of this mode is DSD big endian format, when
user needs this format, then this mode is enabled.

This mode is only for the i.MX943 platform currently.
