Introduce a new carveout for modem metadata. This will serve as a
replacement for the memory region used by MSA to authenticate modem

Thank you for your patch. There is something to discuss/improve.

Only two memory regions are allowed by bindings... unless you fix it in
further patchset. If so, please re-order to have the bindings first. It
helps reviewers not to have such questions. :)
I felt that Rob's dt_bindings check bot might report an error
if the dt changes weren't placed before the bindings changes.
But since you asked for the logical order I guess the bindings
check are done only after the entire series is applied. I'll
change the order in the next re-spin.
