Add buffer token SOF_TKN_BUF_TYPE, for different buffer type. Add a new W_BUFFER_DMA function which will allocate buffer with DMA type.

cant we just add an arg to W_BUFFER for memory type ?
I planed to use that, but it need change too much(in almost each platform .m4 files)
add one W_BUFFER_DMA here is friendly for BYT/CHT/BDW/HSW, and even for normal buffers(non-dma ones, buffers inside FW).
Thanks, ~Keyon
