[PATCH] drm/armada: fix debugfs link error

[Arnd Bergmann]

Debugfs can be disabled at compile time, causing a link error
with the newly restructured code:

drivers/gpu/drm/armada/armada_crtc.o: In function `armada_drm_crtc_late_register':
armada_crtc.c:(.text+0x974): undefined reference to `armada_drm_crtc_debugfs_init'

Make the code into the debugfs init function conditional.

Fixes: 05ec8bd524ba ("drm/armada: redo CRTC debugfs files")
