[PATCH] gpu: nova-core: write initial RPCs before booting GSP-RM

[Timur Tabi <ttabi@nvidia.com>]

Make sure that the two setup RPCs, SetSystemInfo and SetRegistry, are in
the command queue before booting GSP-RM.  These message are expected to
already be present, because GSP-RM will process the queue early in boot
but will silently ignore the error if absent.  GSP-RM then continues
booting, but since the registry is not set up, it fails to initialize.
