[Intel-xe] [PATCH v4 0/2] Add gtidle properties

[Riana Tauro]

      Add gtidle sysfs interface under device/../gt#/
Currently there are three properties name, idle_status and
idle_residency

These display both media and render c state properties according
to gt

The new sysfs structure will have the below layout

/sys/bus/.../bdf
             ├── gt0
             │   └── gtidle
             │       ├── idle_residency_ms
             │       ├── idle_status [gt-c6, gt-c0]
             │       └── name [gt#-rc, gt#-mc]
             ├── gtN
             │   └── gtidle
             │       ├── idle_residency_ms
             │       ├── idle_status
             │       └── name
