video: panel: add Sharp LQ079L1SX01 MIPI DSI panel driver
This module is a color active matrix LCD module incorporating Oxide TFT (Thin Film Transistor). It is composed of a color TFT-LCD panel, driver ICs, a control circuit and power supply circuit, and a backlight unit. Graphics and texts can be displayed on a 1536x2048 dots panel with (16,777,216) colors by using MIPI DUAL DSI interface, supplying +3.3V DC supply voltage for TFT-LCD panel driving and supplying DC supply voltage for LED Backlight.
