[PATCH v5 01/20] drm/panel: panel-simple: Add missing pm_runtime_disable() calls

[Douglas Anderson]

In commit 3235b0f20a0a ("drm/panel: panel-simple: Use runtime pm to
avoid excessive unprepare / prepare") we started using pm_runtime, but
my patch neglected to add the proper pm_runtime_disable(). Doh! Add
them now.
