serial: sh-sci: suppress warning for ports without dma channels If a port has no dma channel defined in the device tree, then don't attempt to allocate a dma channel for the port. Also suppress the warning message concerning the failure to allocate a dma channel. Continue to emit the warning message if a dma channel is defined but cannot be allocated.
