drm/omap: displays: panel-dpi: Support for handling backlight devices
The associated backlight device can be configured via DT by providing the
phandle to the device.
If the backlight device is configured, the driver can manage the backligt
along with the panel's power state, iow it can turn on the backlight when
the panel is enabled and turn it off when the panel is disabled.
