[PATCH 1/3] drm/panel: simple: Make panel_simple_remove() return void

[Uwe Kleine-König <u.kleine-koenig@xxxxxxxxxxxxxx>]

panel_simple_remove() returns zero unconditionally. Make it return no value
instead making more obvious what happens in the callers.

This is a preparation for making platform and mipi-dsi remove callbacks
return void.
