drm/panel: boe-tv101wum-nl6: make use of prepare_prev_first

Browse Source 
[ Upstream commit 42a7a16bedc991190310a02dd202e29cfac52525 ]

The panel on sc7180-trogdor-wormdingler and
sc7180-trogdor-quackingstick hasn't been coming up since commit
9e15123eca79 ("drm/msm/dsi: Stop unconditionally powering up DSI hosts
at modeset"). Let's add "prepare_prev_first" as has been done for many
other DSI panels.

Fixes: 9e15123eca79 ("drm/msm/dsi: Stop unconditionally powering up DSI hosts at modeset")
