From: Ranjani Sridharan ranjani.sridharan@linux.intel.com
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.
