[PATCH 2/4] Revert "drm/mediatek: dsi: Fix DSI host and panel bridge pre-enable order"

[Tomi Valkeinen <tomi.valkeinen@ideasonboard.com>]

This reverts commit f5b1819193667bf62c3c99d3921b9429997a14b2.

As the original commit (c9b1150a68d9 ("drm/atomic-helper: Re-order
bridge chain pre-enable and post-disable")) causing the issue has been
reverted, let's revert the fix for mediatek.
