[Intel-gfx] [PATCH v3 8/9] drm/i915/xehpsdv: Store lmem region in gt

[Anshuman Gupta]

From: Tvrtko Ursulin <tvrtko.ursulin at intel.com>

Store a pointer to respective local memory region in intel_gt so it can be
used when memory local to a GT needs to be allocated.

v2:
- Use forward decalaration instead of heder file. [Jani]
