[PATCH v2 3/3] drm/bridge: analogix_dp: remove the panel prepare/unprepare in suspend/resume

[Yakir Yang <ykk@rock-chips.com>]

We already manager the panel power status in bridge_disable and
connector->detect functions, then we don't need to manager the
panel power status at suspend/resume in particular.
