Some boards connect the LCD_RESET pin to a reset input on the display panel. On these boards, this pin must be set to the proper level for the display to function. This adds an optional "reset-active" property to the "display" subnode such that devicetrees can specify the desired polarity of the LCD_RESET pin.
