[PATCH 24/35] drm/panel: use the orientation from the panel core

[Dmitry Baryshkov <dmitry.baryshkov@oss.qualcomm.com>]

The panel core handles the "rotation" property now, so the drivers' own
copies are redundant.

ili9881c keeps overriding the value for the 180 degree rotation, the
panel performs that one in the hardware. The -ENODEV exemption in
renesas-r63419 was dead code, drm_of_get_panel_orientation() never
returns that.
