drm/i915: add a debugfs entry for power domain info
Add a debugfs entry showing the use-count for all power domains of each
power well.
v3: address comments from Paulo:
- simplify power_domain_str() by using a switch table
- move power_well::domain_count to power_domains
- WARN_ON decrementing a 0 refcount
