Uwe Kleine-König 79abca2b39 drm/mipi-dsi: Make remove callback return void 
All implementations return 0 and the return value of mipi_dsi_drv_remove()
is ignored anyhow.

So change the prototype of the remove function to return no value. This
way driver authors are not tempted to assume that passing an error to
the upper layer is a good idea. All drivers are adapted accordingly.
There is no intended change of behaviour.
