[RFT PATCH v2 46/48] drm/panel: sony-acx565akm: Don't double-check enabled state in disable

[Douglas Anderson]

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.

The acx565akm seems to do some unique stuff with the "enabled"
state. Specifically:
1. It seems to detect the enabled state based on how the bootloader
   left the panel.
2. It uses the enabled state to prevent certain sysfs files from
   accessing a disabled panel.

We'll leave the "enabled" state tracking for this. However, we can at
least get rid of the double-check when trying to disable.
