drm/panel: sony-td4353-jdi: Enable prepare_prev_first
The DSI host must be enabled before our prepare function can run, which
has to send its init sequence over DSI. Without enabling the host first
the panel will not probe.
Fixes: 9e15123eca79 ("drm/msm/dsi: Stop unconditionally powering up DSI hosts at modeset")
