ASoC: SOF: ipc4-topology: Fix pipeline params at the output of copier

Today, the prepare op for the copier only modifies the sample format in
the pipeline_params to match that of its output format. But consider the
case when a copier is connected to an SRC like below:

copier.SSP.1.1 -> src.1.1 -> copier.host.1.1

Let's say we want to capture 44.1K 32bit 2ch audio and that the sampling
frequency is fixed to 48KHz at the copier.SSP.1.1. pipeline_params starts
off being the same as that as the fe_params, so the rate will be
44.1KHz at the start. But since the copier.SSP.1.1 only captures at
48KHz, the pipeline_params must be changed to match this rate, so that
the SRC prepare op can use this as the reference for selecting the input
audio format.
