Subject: [PATCH v2 1/4] dt-bindings: display: panel: Add KD101NE3-40TI support

Create a new dt-scheam for the kd101ne3-40ti.
The bias IC of this kindisplay-kd101ne3 panel is placed
on the panel side, so when the panel is powered on,
there is no need to control AVDD and AVEE in the driver.

Chage since V2:

-  Drop some properties that have already been defined in panel-common.
-  The header file 'dt-bindings/gpio/gpio.h' is not used, delete it

V1: https://lore.kernel.org/all/20240418081548.12160-2-lvzhaoxiong@huaqin.corp-partner.google.com/
