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

[Imre Deak <imre.deak@xxxxxxxxx>]

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.
