Samsung AMS561RA01 is an AMOLED panel, using the Samsung S6E8AA5X01 MIPI
DSI controller. Implement a basic panel driver for such panels.
The driver also initializes a backlight device, which works by changing
the panel's gamma values and aid brightness levels appropriately, with
the help of look-up tables acquired from downstream kernel sources.
