drm/i915: extract i915_sysfs.h from i915_drv.h It used to be handy that we only had a couple of headers, but over time i915_drv.h has become unwieldy. Extract declarations to a separate header file corresponding to the implementation module, clarifying the modularity of the driver. Ensure the new header is self-contained, and do so with minimal further includes, using forward declarations as needed. Include the new header only where needed, and sort the modified include directives while at it and as needed. No functional changes.

drm/i915/gt: create per-tile sysfs interface Now that we have tiles we want each of them to have its own interface. A directory "gt/" is created under "cardN/" that will contain as many diroctories as the tiles. In the coming patches tile related interfaces will be added. For now the sysfs gt structure simply has an id interface related to the current tile count. The directory structure will follow this scheme: /sys/.../card0 └── gt ├── gt0 │ └── id : : └─- gtN └── id This new set of interfaces will be a basic tool for system managers and administrators when using i915.
