ASoC: SOF: Modify the host trace_init parameter list to include dmab 

Stop host code (AMD, Intel) to access sdev->dmatb directly.
Modify the trace_init prototype to include the pointer to a
struct snd_dma_buffer. The ipc3-dtrace passes for now the pointer to
sdev->dmatb, but the aim is to move all tracing related runtime information
local to a trace implementation.
