[PATCH openbmc v2 6/7] palmetto: Build devicetrees for hardware and QEMU

[OpenBMC Patches]

From: Andrew Jeffery <andrew at aj.id.au>

Using a separate devicetree for QEMU allows us to integrate existing
models for hardware features, compromising on accuracy but hopefully
providing a net benefit by reducing development time.
