To support multi-GT configurations, we need to generate
independent debug files for each GT.
To achieve this create a separate directory for each GT under the
debugfs directory. For instance, in a system with two GTs, the
debugfs structure would look like this:
/sys/kernel/debug/dri
└── 0
├── gt0
│ ├── drpc
│ ├── engines
│ ├── forcewake
│ ├── frequency
│ └── rps_boost
└── gt1
: ├── drpc
: ├── engines
: ├── forcewake
├── frequency
└── rps_boost
