Thomas Zimmermann 1f828b4dd4 drm/client: Make client support optional
Only build client code if DRM_CLIENT has been selected. Automatially
do so if one of the default clients has been enabled. If client support
has been disabled, the helpers for client-related events are empty and
the regular client functions are not present.

Amdgpu has an internal DRM client, so it has to select DRM_CLIENT by
itself unconditionally.

v3:
- provide empty drm_client_debugfs_init() if DRM_CLIENT=n (kernel
  test robot)
