ASoC: SOF: ipc4-topology: Do not parse the DMA_BUFFER_SIZE token 

Do not parse the SOF_TKN_CAVS_AUDIO_FORMAT_DMA_BUFFER_SIZE token as the
dma_buffer_size can be derived from the input/output buffer size and the
type of widget during copier prepare. For the deep buffer case,
introduce a new token that will be used to get the deep buffer DMA size
for the host copier from topology.
