Since old firmware on VIC cannot support context isolation without hacks that we don't want to implement, check the firmware binary to see if context isolation should be enabled.

Add channel stopping to RPM suspend callback. Add system level suspend-resume callbacks. Runtime PM initialization is moved to host1x client init phase because RPM callback now uses host1x channel that is available only when host1x client is registered.

If that does happen, passing some uninitialised stack contents to dma_mapping_error() - which belongs to a different API in the first place - has precious little chance of detecting it. Also include the correct header, because the fragile transitive inclusion currently providing it is going to break soon.
