drivers: mtk: get memif format from config of DAI component 

MTK memif(DMA) can support different format from BE dai, so we don't
need to rely on the transformation of SOF DAI. After the patch, the
format of memif follows DAI component, so the format can be kept the
same in the pipeline and do format transformation via AFE if
necessary.
