[PATCH v4 3/3] drm/panel: add support for Innolux TV123WAM panel

[Sandeep Panda]

Innolux TV123WAM is a 12.3" eDP display panel with
2160x1440 resolution, which can be supported by simple
panel driver.

Changes in v1:
 - Make use of simple panel driver instead of creating
   a new driver for this panel (Sean Paul).
 - Combine dt-binding and driver changes into one patch
   as done by other existing panel support changes.
