drm: Add drm_plane/connector_index
In the atomic state we'll have an array of states for crtcs, planes
and connectors and need to be able to at them by their index. We
already have a drm_crtc_index function so add the missing ones for
planes and connectors.
If it later on turns out that the list walking is too expensive we can
add the index to the relevant modeset objects.
Rob Clark doesn't like the loops too much, but we can always add an
obj->idx parameter later on. And for now reiterating is actually safer
since nowadays we have hotpluggable connectors (thanks to DP MST).
v2: Fix embarrassing copypasta fail in kerneldoc and header
declarations, spotted by Matt Roper.
