[PATCH] drm/i915/gvt: clean up kernel-doc in gtt.c

[Randy Dunlap]

Fix kernel-doc warnings in gtt.c:

gtt.c:1152: warning: This comment starts with '/**', but isn't a kernel-doc comment. Refer Documentation/doc-guide/kernel-doc.rst
 * Check if can do 2M page
gtt.c:1152: warning: missing initial short description on line:
 * Check if can do 2M page
gtt.c:2209: warning: expecting prototype for intel_vgpu_emulate_gtt_mmio_read(). Prototype was for intel_vgpu_emulate_ggtt_mmio_read() instead

Fixes: a752b070a678 ("drm/i915/gvt: Fix function comment doc errors")
Fixes: 2707e4446688 ("drm/i915/gvt: vGPU graphics memory virtualization")
