Changes to access sysfs entries under tile directory.
Access freq sysfs from /sys/class/drm/cardX/device/tileN/gtN
path.
v2:
- Use snprintf instead of sprintf and check error.
- Describe what changes are done. (Kamil)
v3:
- change order of gt and tile and drop passing tilecount.(Ashutosh)
v4:
- Rebase
v5:
- Drop usage of xe_for_each_gt_under_each_tile and use
a function to return gt path. (Ashutosh)
