Using compound literals for initialization can be tricky. Lacking a
const qualifier, they won't end up in rodata, which is probably not
expected or intended. Add const to move a whopping 136 initializers to
rodata.
Compare:
$ objdump --syms drivers/gpu/drm/i915/display/intel_display_power_map.o | grep "\.rodata.*__compound_literal"
$ objdump --syms drivers/gpu/drm/i915/display/intel_display_power_map.o | grep "\.data.*__compound_literal"
Before and after the change.

Fixes: 4a845ff0c0d4 ("drm/i915: Simplify power well definitions by adding power well instances")
