[PATCH v3 4/7] drm/bridge: ti-sn65dsi86: Move panel_prepare() to pre_enable()

[Sean Paul <sean@poorly.run>]

From: Sean Paul <seanpaul@chromium.org>

prepare() is the old-timey way to say pre_enable(). It should be called
before modeset. This fixes an issue where the panel on cheza must have
the regulator always-on/boot-on for it to work.

Changes in v3:
- Added to the set
