drm/panel: otm8009a: Set backlight parent to panel device
commit ab4f869fba6119997f7630d600049762a2b014fa upstream.
This is the logical place to put the backlight device, and it also
fixes a kernel crash if the MIPI host is removed. Previously the
backlight device would be unregistered twice when this happened - once
as a child of the MIPI host through `mipi_dsi_host_unregister`, and
once when the panel device is destroyed.
