[Intel-gfx] [PATCH v2 09/10] drm/i915: Use existing power well IDs where possible

[Imre Deak]

There is no need for separate IDs for power wells on a new platform with
the same functionality as an other power well on a previous platform, we
can just reuse the ID from the previous platform. This is only possible
after the previous patches where we removed dependence on the actual
enum values.

v2:
- Keep an ID assigned for the ICL PW#2 power well too. (Paulo)
