tty: amba-pl011: don't dereference NULL platform data When only a TX DMA channel is specified in DT, pl011_dma_probe() falls back to looking for the optional RX channel in platform data. What it doesn't do is check whether that platform data actually exists... Add the missing check to avoid crashing the kernel.
