drm/client: Fix drm client endless Kconfig loop

if DRM_CLIENT_SELECTION is enabled, and none of the client is, the
"Default DRM Client" choice is empty, and this makes Kconfig goes
into an infinite loop of:

  Default DRM Client
  choice[1-0?]: 0
  Default DRM Client
  choice[1-0?]: 0
  Default DRM Client
  choice[1-0?]: 0
  ....

So only allow the choice if at least one of the client is selected.
