The iommu-map property in the fsl-mc node is updated by valid stream-ids by u-boot. This patch is to fixup this property for LS208x and LS1088.

Signed-off-by: Nipun Gupta nipun.gupta@nxp.com --- This patch fixes iommu-map property added for fsl-mc in kernel patch series: https://patchwork.kernel.org/patch/10594185/ Kernel patch series is accepted and would be available in kernel 4.20.

This patch is backward compatible and have only a debug log if the property is not found in kernel.
