Brad Griffis 774f55c736 t23x: overlay: add no-map to vpr carveout ...

The VPR carveout has special security constraints. It must not be
read by the CPU. Add "no-map" property to this region to avoid
issues.

Currently linux-next builds are failing to boot because we hit
an error related to this mapping.

Addition of no-map resolves the issue.
