drm/panel: simple: Add missing panel_simple_unprepare() calls
commit f3621a8eb59a913612c8e6e37d81f16b649f8b6c upstream.
During panel removal or system shutdown panel_simple_disable() is called
which disables the panel backlight but the panel is still powered due to
missing calls to panel_simple_unprepare().
Fixes: d02fd93e2cd8 ("drm/panel: simple - Disable panel on shutdown")
