gsp-phys: register the RM log ring correctly, send raw config-space identity, and request the full static-config payload
The RM log-ring init argument carried a malformed libos id (LOGM), so the
server never mapped the ring and its early failure path was invisible.
The pre-boot system-info payload carried unpacked 16-bit identity fields;
the server expects the raw config-space dwords (device<<16|vendor), so its
GPU device-id read back as zero and the static-config device-name lookup
returned NOT_SUPPORTED.
The static-config RPC must be sized to the full reply payload, and the
guest-system-info RPC is sent first, matching the reference order.
Live result: GSP-RM completes initialization (init-done rpc_result=0),
serves the 1656-byte static config (name, FB size, handles, PDE bases),
and shuts down cleanly through the unload RPC.
