Series drm/panel: Remove most store/double-check of prepared/enabled state | expand

As talked about in commit d2aacaf07395 ("drm/panel: Check for already
prepared/enabled in drm_panel"), we want to remove needless code from
panel drivers that was storing and double-checking the
prepared/enabled state. Even if someone was relying on the
double-check before, that double-check is now in the core and not
needed in individual drivers.

- Split removal of prepared/enabled from handling of remove/shutdown.

Hi Douglas Anderson,

Poco F1 is one of the main user for this panel. I tested the patch in my Poco F1 running postmarketOS. It works fine. Thank you. The panel itself requires other extra fixes to work properly which I intend to upstream in the upcoming weeks. But your patch doesn't break anything and works as expected. So.
