Enable the drm panel prepare_prev_first flag for feixin-k101-im2ba02
so-that the previous controller should be prepared first before the
prepare for the panel is called.
This makes sure that the previous controller(sun6i-mipi-dsi), likely to
be a DSI host controller should be initialized to LP-11 before the panel
is powered up.
