Ugh, ignore the above paragraph. I managed to confuse myself and was
thinking about shutdown but talking about remove. Sigh. :( Instead,
pretend the above paragraph said:

As per our discussion, in V2 we will make drm_panel_remove() actually
unprepare / disable a panel (and print a warning) if it was left
enabled. This would essentially fold in the
drm_panel_helper_shutdown() from my RFC patch (but add a warning).
This would make tdo_tl070wsh30_panel_remove() behave the same as it
did before with the addition of a warning if someone tries to remove a
currently powered panel.
