[igt-dev] [PATCH i-g-t] lib/intel_memory_region: Constify info structures

[Janusz Krzysztofik]

Functions which extract information from drm_i915_query_memory_regions
structures passed via their pointer as an argument don't modify those
structures, let them accept that content declared as constant.
