SK-AM62: modify the hdmi LCD bit depth from 24bit to 16bit

Hello,

The depth would be defined in your userspace application code. Depending on the framework being used, they usually give an option for the depth field. Here is a reference document: https://www.khronos.org/opengl/wiki/Image_Format

what is the meaning of "Depending on the framework being used“？

For example, if you are using Qt framework they will have a mechanism to configure the depth buffer. If you are using native opengles, it will have it's own mechanism for selecting depth buffer. In summary, your custom userspace application will need to select the appropriate depth buffer.
