[SLOF] [PATCH slof v4 3/3] rtas: Store RTAS address and entry in the device tree

[Alexey Kardashevskiy]

At the moment we count on the guest kernel to update or create device
tree properties pointing to the instantiated RTAS copy which is not
very reliable.

This stores rtas-base and rtas-entry in the DT at the instantiation
point so later on the H_UPDATE_DT hcall can supply QEMU with an updated
location of RTAS.

This superseeds f9a60de30 "Add private HCALL to inform updated
RTAS base and entry".
