On a multi-tile platform, each tile has its own registers + GGTT space, and BAR 0 is extended to cover all of them. Up to four GTs are supported in i915->gt[], with slot zero shadowing the existing i915->gt0 to enable source compatibility with legacy driver paths. A for_each_gt macro is added to iterate over the GTs and will be used by upcoming patches that convert various parts of the driver to be multi-gt aware. Only the primary/root tile is initialized for now; the other tiles will be detected and plugged in by future patches once the necessary infrastructure is in place to handle them.
