In the view of multi-gt we want independent per gt debug files.

In debugfs create gt0/ gt1/ ... gtN/ for tile related files. In 4
tiles, the debugfs would be structured as follows:

/sys/kernel/debug/dri
                  └── 0
                      ├── gt0
                      │   ├── drpc
                      │   ├── engines
                      │   ├── forcewake
                      │   ├── frequency
                      │   └── rps_boost
                      ├── gt1
                      │   ├── drpc
                      │   ├── engines
                      │   ├── forcewake
                      │   ├── frequency
                      │   └── rps_boost
                      ├── gt2
                      │   ├── drpc
                      │   ├── engines
                      │   ├── forcewake
                      │   ├── frequency
                      │   └── rps_boost
                      └─- gt3
                      :   ├── drpc
                      :   ├── engines
                      :   ├── forcewake
                          ├── frequency
