drm/panel: sony-td4353-jdi: Enable prepare_prev_first

Browse Source 
[ Upstream commit 2b973ca48ff3ef1952091c8f988d7796781836c8 ]

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: 9e15123eca ("drm/msm/dsi: Stop unconditionally powering up DSI hosts at modeset")
