Subject: [PATCH v3 1/3] dt-bindings: reserved-memory: rmtfs: Make qcom,vmid an array

Some SoCs mandate that the RMTFS is also assigned to the NAV VM, while
others really don't want that. Since it has to be conditional, turn
qcom,vmid into an u32 array so that we can handle the NAV case, as
well as other similar ones if they pop up in the future.
