drm: Always include the debugfs dentry in drm_crtc

Remove the counterproductive CONFIG_DEBUG_FS ifdef and just include
the debugfs dentry in drm_crtc always. This way we don't need
annoying ifdefs in the actual code with DEBUGFS=n. Also we don't
have these ifdefs around any of the other debugfs dentries either
so can't see why drm_crtc should be special.

This fixes the i915 DEBUGFS=n build because I assumed the dentry
would always be there.
