drm/i915/lmem: debugfs for LMEM details
Debugfs i915_gem_object is extended to enable the IGTs to
detect the LMEM's availability and the total size of LMEM.
v2: READ_ONCE is used [Chris]
v3: %pa is used for printing the resource [Chris]
v4: All regions' details added to debugfs [Chris]
v5: Macro for_each_mem_region added
name is initialized at region init [Chris]
