gpu: nova-core: Implement the GSP sequencer

Browse Source 
Implement the GSP sequencer which culminates in INIT_DONE message being
received from the GSP indicating that the GSP has successfully booted.

This is just initial sequencer support, the actual commands will be
added in the next patches.

Signed-off-by: Joel Fernandes <joelagnelf@nvidia.com>
[acourbot@nvidia.com: move GspSequencerInfo definition before its impl
blocks and rename it to GspSequence, adapt imports in sequencer.rs to
new formatting rules, remove `timeout` argument to harmonize with other
commands.]
