drm/i915/uc: Move uC debugfs to its own folder under GT
uC is a component of the GT, so it makes sense for the uC debugfs files
to be in the GT folder. A subfolder has been used to keep the same
structure we have for the code.
v2: use intel_* prefix (Jani), rebase on new gt_debugfs_register_files,
fix permissions for writable debugfs files.
v3: Rename files (Michal), remove blank line (Jani), fix sparse warns.
