i2c: tegra: Allocate DMA memory for DMA engine

Browse source

When the I2C controllers are running in DMA mode, it is the DMA engine
that performs the memory accesses rather than the I2C controller. Pass
the DMA engine's struct device pointer to the DMA API to make sure the
correct DMA operations are used.

This fixes an issue where the DMA engine's SMMU stream ID needs to be
misleadingly set for the I2C controllers in device tree.
