Subject: drm/amdgpu/display: fix build when CONFIG_DEBUG_FS is not set
Git-commit: c0c87382c1a6985cd12a49a62a893361e5fd1b8f
Patch-mainline: v6.0-rc1
References: jsc#PED-1166 jsc#PED-1168 jsc#PED-1170 jsc#PED-1218 jsc#PED-1220 jsc#PED-1222 jsc#PED-1223 jsc#PED-1225 jsc#PED-2849

amdgpu_dm_crtc_late_register() is only used when CONFIG_DEBUG_FS
is enabled so make it dependent on that.
