drm/bridge: tc358762: Set pre_enable_prev_first

Set the "pre_enable_prev_first" as provided by commit 4fb912e5
("drm/bridge: Introduce pre_enable_prev_first to alter bridge init
order"). This should allow us to revert commit ec7981e6
("drm/msm/dsi: don't powerup at modeset time for parade-ps8640") and
commit 7d8e9a90 ("drm/msm/dsi: move DSI host powerup to modeset
time").
