drm/i915: Constify power well descriptors
It makes sense to keep unchanging data const. Extract such fields from
the i915_power_well struct into a new i915_power_well_desc struct that
we initialize during compile time. For the rest of the dynamic
fields allocate an array of i915_power_well objects in i915 dev_priv,
and link to each of these objects their corresponding
i915_power_well_desc object.
v2:
- Fix checkpatch warnings about missing param name in fn declaration and
lines over 80 chars. (Paulo)
- Move check for unique IDs to __set_power_wells().
