In such a way that vcs and vcs2 are just two different instances (0 and 1)
of the same engine class (VIDEO_DECODE_CLASS).

v2: Align the instance types (Tvrtko)

Hmm, if this 'class' identifiers are related to the hw then maybe we should
move these definitions into i915_reg.h in similar way as it was done in

	237ae7c79e26 drm/i915: Don't use enums for hardware engine id

and here just keep class as "u8"

Yup, I presume they are hw/bsepc related due to the explicit use of
numbering. We might start being more honest with ourselves and calling
it intel_engine_bspec.h :)
