gsp_rm: implement missing RM_CONTROL handlers for 570.144 guest driver
- Added TU104_CTRL_INTERNAL_MEMSYS_L2_INVALIDATE_EVICT (0x20800a6c)
- Added TU104_CTRL_INTERNAL_GR_GET_FECS_TRACE_HW_ENABLE (0x20800a38)
- Added TU104_CTRL_SYSTEM_MAP_SHARED_DATA (0x730151)
- Fixed async RPCs (72 GSP_SET_SYSTEM_INFO, 73 SET_REGISTRY, 71 CONTINUATION_RECORD)
to send SUCCESS replies instead of silent consume
- Added explicit handlers for RPC 47 (UNLOADING_GUEST_DRIVER) and 70 (UPDATE_BAR_PDE)
with proper reply semantics
Guest driver was failing at GSP-RM level with unknown RPCs 47, 70, 72, 73.
Channels registered then immediately unregistered.
Now they should stay registered and complete initialization.
