PAPR requires every property listed in its table of /rtas device tree properties to be present before the OS is booted (R-7.2.6-3 and Table 20 in PAPR v10.60; the same requirement is in LoPAR 2.9 and LoPAPR 1.1). One of them is "rtas-version", an integer encoding of the RTAS interface version, and PAPR says it describes version 1 of that interface. spapr_dt_rtas() sets "rtas-size", "rtas-error-log-max" and "rtas-event-scan-rate" but never "rtas-version", so a client that reads it finds no RTAS: NetBSD's RTAS driver fails to attach when the property is absent. Set it to 1, the version PAPR describes.
