misc: fastrpc: Add dma_mask to fastrpc_channel_ctx
dma_set_mask_and_coherent only updates the mask to which the device dma_mask pointer points to. Add a dma_mask to the channel ctx and set the device dma_mask to point to that, otherwise the dma_set_mask will return an error and the dma_set_coherent_mask will be skipped too.
