[0/2] Add module parameter to reduce engine instances

Message

Add a new module parameter, ring_mask, to allow users to
disable certain engines for a platform. By default this
mask is set to all engines enabled. Bits in the mask are
aligned with the intel_engine_id enums.

As a prerequisite to the patch which adds the module parameter,
change the BUG_ON to a WARN_ON in the event a VDbox or VEbox
engine for a platform does not match the total number of engines
of these catagories supported in the corresponding fuses.
