gsp-phys: command-queue TX and the GSP-RM unload RPC for clean teardown
Adds a minimal msgq producer on the command queue (element layout, checksum, sequence, dma_wmb before writePtr, doorbell) and submits the UNLOADING_GUEST_DRIVER RPC so GSP-RM shuts down and sets the scratch14 handoff bit the Booter Unload gate needs. Release attempts the RPC once before quiescing when a boot ran; on-demand testing is available through the debugfs file gsp-phys-unload-rpc while the module owns the GPU. GSP-RM processor suspend is polled on the GSP mailbox.
