dt-bindings: display: sitronix,st7571: add optional inverted property



Depending on which display that is connected to the controller, an "1"
means either a black or a white pixel.

The supported formats (R1/R2/XRGB8888) expects the pixels
to map against (4bit):
00 => Black
01 => Dark Gray
10 => Light Gray
11 => White

If this is not what the display map against, the controller has support
to invert these values.
