Luca Ceresoli e4cedfd4f0 drm/bridge: add drm_bridge_is_last() ...

Some code needing to know whether a bridge is the last in a chain currently
call drm_bridge_get_next_bridge(). However drm_bridge_get_next_bridge()
will soon increment the refcount of the returned bridge, which would make
such code more annoying to write.

In preparation for drm_bridge_get_next_bridge() to increment the refcount,
as well as to simplify such code, introduce a simple bool function to tell
whether a bridge is the last in the chain.
