[PATCH] drm/msm: Don't attempt to attach HDMI bridge twice

[Bjorn Andersson]

With the introduction of '3ef2f119bd3e ("drm/msm: Use
drm_attach_bridge() to attach a bridge to an encoder")' the HDMI bridge
is attached both in msm_hdmi_bridge_init() and later in
msm_hdmi_modeset_init().

The second attempt fails as the bridge is already attached to the
encoder and the whole process is aborted.

So instead make msm_hdmi_bridge_init() just initialize the hdmi_bridge
object and let msm_hdmi_modeset_init() attach it later.

Fixes: 3ef2f119bd3e ("drm/msm: Use drm_attach_bridge() to attach a bridge to an encoder")
