tty: serial: fsl_lpuart: use dmaengine_get_dma_device() for DMA mapping
Replace all chan->device->dev references with
dmaengine_get_dma_device(chan) so that DMA mapping goes through the
correct device when the DMA controller has per-channel IOMMU domains
(chan_dma_dev=true). Without this, DMA map/unmap/sync bypasses the
IOMMU context configured by the eDMA driver.
