There isn't any fundamental thing tying device tree to a given architecture or 32bitness, it's just that sane PC architectures use ACPI to enumerate devices, and/or have a discoverable bus architecture. Some of the phones don't so this now becoems a point of consideration. In fact it's already also used on CE4100 (which is an embedded media SoC found in some TV devices and set-top boxes) and on the OLPC (One laptop per child). There is no intrinsic reason it couldn't be used in other x86 special cases. If its PC shaped however it probably has ACPI and ACPI and DT are not a 1:1 mapping. ACPI has method invocations, and various firmware provided interfaces such as the EC, Device tree is better at some other bits. Converting the phones to embedded device tree rather than adding a billion little platform files on the other hand seems to me like a no-brainer.
