drm/i915: Use existing power well IDs where possible

Browse source

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.

This also fixes a problem on ICL where in assert_can_enable_dc5/9() we
would've failed to look up the PW#2 power well.

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