[PATCH] drm/amd/display: add debugfs entry for trigger_hotplug

[Jason Yan]

The 'trigger_hotplug' entry in debugfs is defined but not wired up. This
causes a gcc warning build with W=1.

drivers/gpu/drm/amd/amdgpu/../display/amdgpu_dm/amdgpu_dm_debugfs.c:2045:37:
warning: ‘dp_trigger_hotplug_debugfs_fops’ defined but not used
[-Wunused-const-variable=]
 2045 | static const struct file_operations
      dp_trigger_hotplug_debugfs_fops = {
      |
