[PATCH 6/6] drm/i915: Implement fdinfo memory stats printing

[Andi Shyti]

Hi Tvrtko,

> Use the newly added drm_print_memory_stats helper to show memory
> utilisation of our objects in drm/driver specific fdinfo output.
> 
> To collect the stats we walk the per memory regions object lists
> and accumulate object size into the respective drm_memory_stats
> categories.
> 
> v2:
>  * Only account against the active region.
>  * Use DMA_RESV_USAGE_BOOKKEEP when testing for active. (Tejas)
> 
> v3:
>  * Update commit text. (Aravind)
>  * Update to use memory regions uabi names.
