[Intel-gfx] [PATCH i-g-t 3/6] intel_gpu_top: Add command line switch to start in physical engine mode

[Tvrtko Ursulin <tvrtko.ursulin@linux.intel.com>]

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

Default mode is to aggreate engines per class but some users would prefer
to be able to start in physical engine mode too.
