Revert "dt-bindings: display: mediatek: add ethdr definition for mt8195"

This reverts commit e7dcfe64.

Because examples property of mediatek,ethdr.yaml should base on [1][2].
Reverting it until [1][2] are applied.

-description: |
-  ETHDR is designed for HDR video and graphics conversion in the external display path.
-  It handles multiple HDR input types and performs tone mapping, color space/color
-  format conversion, and then combine different layers, output the required HDR or
-  SDR signal to the subsequent display path. This engine is composed of two video
-  frontends, two graphic frontends, one video backend and a mixer. ETHDR has two
-  DMA function blocks, DS and ADL. These two function blocks read the pre-programmed
-  registers from DRAM and set them to HW in the v-blanking period.
