[Intel-gfx] [PATCH i-g-t 2/4] lsgpu: User friendly device listing

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

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

New default user frindly device listing mode which replaces:

sys:/sys/devices/pci0000:00/0000:00:02.0/drm/card0
    subsystem       : drm
    drm card        : /dev/dri/card0
    parent          : sys:/sys/devices/pci0000:00/0000:00:02.0

sys:/sys/devices/pci0000:00/0000:00:02.0/drm/renderD128
   subsystem       : drm
   drm render      : /dev/dri/renderD128
   parent          : sys:/sys/devices/pci0000:00/0000:00:02.0

sys:/sys/devices/pci0000:00/0000:00:02.0
   subsystem       : pci
    drm card        : /dev/dri/card0
    drm render      : /dev/dri/renderD128
    vendor          : 8086
    device          : 193B

With:

card0                   8086:193B    drm:/dev/dri/card0
└─renderD128                         drm:/dev/dri/renderD128

Advantages are more compact, more readable, one entry per GPU.

Legacy format can be chose using the -s / --print-simple command line
switches.
