Realtek LCD controller

Required properties:
- compatible: "realtek,rts3915-lcdc"
- reg: physical base address of the LCD controller and length of memory mapped
region
- interrupt-parent: Phandle of the parent interrupt controller
- interrupts : Should contain the lcd interrupt number
- resets: List of phandle and reset specifier pairs, one pair for
each reset signal that affects the device
- reset-names: List of reset signal name strings sorted in the same order as
the resets property

Example:

	lcdcif: lcdcif@18c00000 {
		compatible = "realtek,rts3915-lcdc";
		reg = <0x18C00000 0x1000>;
		interrupt-parent = <&vecintc>;
		interrupts = <BSP_IRQ_LCDC>;
		resets = <&reset FORCE_RESET_DRAM_LCDC>,	\
				<&reset SYS_MEM_SD_LCDC>;
		reset-names = "rst", "sd";
		status = "disabled";
	};
