  1. drm/panel: ilitek-ili9881c: Clean up on mipi_dsi_attach failure 

    mipi_dsi_attach is allowed to fail, and currently the probe
code doesn't clean up (mainly drm_panel_remove) if this happens.

Add cleanup code on failure.

  2. drm/panel: panel-ilitek9881c: Add prepare_upstream_first flag 

    The panel sends MIPI DCS commands during prepare and is expecting
the bus to remain in LP-11 state in-between.

Set the prepare_upstream_first flag so that the upstream DSI host
is prepared / pre_enabled first, and therefore the bus is in a
defined state.
