Having removed the urge to modify the engine_mask at runtime, we can
promote the num_engines from a runtime calculation to a static and push
it into the device_info tables.
What about fused off engines (intel_device_info_init_mmio)?
Didn't notice. :((
Plan B was just to calculate num_engines at point of use, since it is
rare enough.
I'd just leave it in runtime info for now. Don't see a benefit of moving it.
If I can find my last series which tried to eliminate mkwrite and reduce
runtime info, there were some notes in the resulting threads about which
fields have what problems associated with them. I only remember the gen
field was looking like easy pickings..
Anyways...
Oh well, this pair of patches was just inspired because I touched the
cleanup code and not important.
.. please restrain the inspiration if ahead of media scalability
otherwise we will never be done with it! :))
