drm/i915: fix the power well ID for always on wells
lookup_power_well() expects uniq power well IDs, but atm we have uninitialized IDs which would clash with those power wells with a 0 ID. This wasn't a problem so far since nothing looked up such a power well, but an upcoming patch will (Misc IO for SKL), so fix this up on platforms where this matters.
