of: Move of_dma_configure() to device.c to help re-use
Move of_dma_configure() to device.c so it can be re-used for PCI devices to
obtain DMA configuration from DT. Also add a second argument so that for
PCI, the DT node of root bus host bridge can be used to obtain the DMA
configuration for the slave PCI device.
