ASoC: SOF: ipc4-pcm: fix delay calculation when DSP resamples
commit bcd1383516bb5a6f72b2d1e7f7ad42c4a14837d1 upstream.
When the sampling rates going in (host) and out (dai) from the DSP
are different, the IPC4 delay reporting does not work correctly.
Add support for this case by scaling the all raw position values to
a common timebase before calculating real-time delay for the PCM.
