[PATCH 1/5] drm/panel: Add support for the EDT ETM0700G0BDH6

[Jan Tuerk]

The Emerging Display Technology ETM0700G0BDH6 is exactly
the same display as the ETM0700G0DH6, exept the pixelclock
polarity. Therefore re-use the ETM0700G0DH6 modes. It is
used by default on emtrion Avari based development kits.
