The dynamic memory region used for metadata authentication would still be a part of the kernel mapping and any access to this region by the application processor after assigning it to the remote Q6 will result in a XPU violation. This is fixed by using a no-map carveout instead. Update the bindings to reflect the addition of the new modem metadata carveout on MSM8996 (and similar) SoCs.
