powerpc/powernv: Check device-tree for RFI flush settings

commit 6e032b350cd1fdb830f18f8320ef0e13b4e24094 upstream.

New device-tree properties are available which tell the hypervisor
settings related to the RFI flush. Use them to determine the
appropriate flush instruction to use, and whether the flush is
required.
