net: lan966x: use a dedicated device for DMA operations
In preparation for the PCIe FDMA implementation, add lan966x->dma_dev,
resolved once at probe time, and use it for every DMA operation the
FDMA path performs: coherent allocations, streaming mappings and the RX
page pool. Natively, dma_dev is lan966x->dev, so there is no functional
change.
Since dma_dev differs from dev only on the PCIe path, add
lan966x_is_pci() on top of it, for the later PCIe patches to key off.
