[ Upstream commit 053d231f369ca05cd563ca9738b5a4c73908e697 ]

The bridge operation '.enable' and the audio cb '.get_eld'
access hdmi->conn. In the future we will want to support
the flag DRM_BRIDGE_ATTACH_NO_CONNECTOR and then we will
not have direct access to the connector.
The atomic version '.atomic_enable' allows accessing the
current connector from the state.
This patch switches the bridge to the atomic version to
prepare access to the connector in later patches.
