>     drm/i915/tgl: Register state context definition for Gen12
>     
>     Gen12 has subtle changes in the reg state context offsets (some fields
>     are gone, some are in a different location), compared to previous Gens.
>     
>     The simplest approach seems to be keeping Gen12 (and future platform)
>     changes apart from the previous gens, while keeping the registers that
>     are contiguous in functions we can reuse.
>     
>     v2: alias, virtual engine, rpcs, prune unused regs
>     v3: use engine base (Daniele), take ctx_bb for all
