drivers: net: fsl-mc: add support for MC reserved memory
Add support for declaring in device tree the reserved memory ranges
required for MC. Since the MC firmware acts as any DMA master present
in the SoC, the reserved memory ranges need also be identity mapped
in the SMMU, so create the required 'iommu-addresses' property in
the reserved memory nodes.
For now this support is used only on LX2160A SoCs.
