video: backlight: support s6e8ax0 panel driver based on MIPI DSI

This patch is amoled panel driver based MIPI DSI interface. S6E8AX0 means it may includes many other ldi controllers, for example, S6E8AA0, S6E8AB0, and so on.

This patch can be modified depending on each panel properites. For example, second parameter of panel condition register can be changed depending on ldi controller or amoled type.
