drm/i915/uncore: add intel_uncore_regs() helper Add a helper for accessing uncore->regs instead of doing it directly. This will help display code reuse with the xe driver.

drm/i915/mtl: Hook up interrupts for standalone media Top-level handling of standalone media interrupts will be processed as part of the primary GT's interrupt handler (since primary and media GTs share an MMIO space, unlike remote tile setups). When we get down to the point of handling engine interrupts, we need to take care to lookup VCS and VECS engines in the media GT rather than the primary. There are also a couple of additional "other" instance bits that correspond to the media GT's GuC and media GT's power management interrupts; we need to direct those to the media GT instance as well.

drm/i915/mtl: Use primary GT's irq lock for media GT When we hook up interrupts (in the next patch), interrupts for the media GT are still processed as part of the primary GT's interrupt flow. As such, we should share the same IRQ lock with the primary GT. Let's convert gt->irq_lock into a pointer and just point the media GT's instance at the same lock the primary GT is using. v2: - Point media's gt->irq_lock at the primary GT lock properly. (Daniele) - Fix jump target for intel_root_gt_init_early errors.

drm/i915/xelpmp: Expose media as another GT Xe_LPM+ platforms have "standalone media." I.e., the media unit is designed as an additional GT with its own engine list, GuC, forcewake, etc. Let's allow platforms to include media GTs in their device info. v2: - Simplify GSI register handling and split it out to a separate patch for ease of review.
