video: tegra: host: Do not panic on hardware timeout
nvhost panics if hardware does not respond within 30 seconds. Remove
this behavior, as it causes problems in emulation and simulation.
Panic should be used only to prevent corruption.
Submits are now given a default timeout of 30 seconds. The clients
can still override with their own timeout value.
MPE doesn't provide the number of slots for context save/restore.
This information is needed to be able to use the submit timeout for
MPE.
