serial: 8250_dw: provide a filter for DMA channel detection
The channel IDs are set to -1 by default. It will prevent dmaengine from trying to provide the first free channel if it fails to allocate exclusive channel. This will fix an issue with ACPI enumerated UARTs that do not support DMA but still end up getting a DMA channel incorrectly.
