[Intel-gfx] [PATCH i-g-t 3/3] intel_gpu_top: Show non-normalized client usage in numeric mode

[Tvrtko Ursulin]

From: Tvrtko Ursulin <tvrtko.ursulin at intel.com>

When numeric display is selected in the interactive mode it is more
descriptive to show client's non-normalized (by number of engines per
class) usage. Rendering of the visual representation (bar) is kept the
same.
