Fix build error when CONFIG_DEBUG_FS is not enabled by adding a stub function for crtc_debugfs_init().
Eliminates this build error:
../drivers/gpu/drm/amd/amdgpu/../display/amdgpu_dm/amdgpu_dm.c: In function ‘amdgpu_dm_crtc_late_register’: ../drivers/gpu/drm/amd/amdgpu/../display/amdgpu_dm/amdgpu_dm.c:6599:2: error: implicit declaration of function ‘crtc_debugfs_init’; did you mean ‘amdgpu_debugfs_init’? [-Werror=implicit-function-declaration] crtc_debugfs_init(crtc); ^~~~~~~~~~~~~~~~~ amdgpu_debugfs_init
