[PATCH v4 3/7] drm/panel: simple: Add Waiken WKS101WX001-WCT panel support

[Frank.Li@oss.nxp.com]

From: Frank Li <Frank.Li@nxp.com>

Add support for the Waiken WKS101WX001-WCT, an industrial-grade 10.1-inch
IPS TFT LCD panel with a capacitive touchscreen.

Although the module advertises LVDS support, enabling LVDS operation
requires hardware modification, including the removal of several on-board
resistors. As there are currently no known users of the LVDS configuration,
only the default interface mode is supported.

If LVDS support is needed in the future, a dedicated driver can be
introduced to handle switching between LVDS and DBI modes.
