dt-bindings: mxsfb: Add new bindings for the MXSFB driver 

Add new DT bindings for new MXSFB driver that is using the
OF graph to parse the video output structure instead of
hard-coding the display properties into the MXSFB node.
The old MXSFB fbdev driver bindings are preserved in the
same file in the "Old bindings" section.

* Freescale MXS LCD Interface (LCDIF)
New bindings:
=============
Required properties:
- compatible: Should be "fsl,imx23-lcdif" for i.MX23.
Should be "fsl,imx28-lcdif" for i.MX28.
- reg: Address and length of the register set for lcdif
- interrupts: Should contain lcdif interrupts
Should be "fsl,imx6sx-lcdif" for i.MX6SX.
- reg: Address and length of the register set for LCDIF
- interrupts: Should contain LCDIF interrupt
- clocks: A list of phandle + clock-specifier pairs, one for each
entry in 'clock-names'.
- clock-names: A list of clock names. For MXSFB it should contain:
- "pix" for the LCDIF block clock
- (MX6SX-only) "axi", "disp_axi" for the bus interface clock
Required sub-nodes:
- port: The connection to an encoder chip.
Example:
lcdif1: display-controller@2220000 {
compatible = "fsl,imx6sx-lcdif", "fsl,imx28-lcdif";
reg = <0x02220000 0x4000>;
interrupts = <GIC_SPI 5 IRQ_TYPE_LEVEL_HIGH>;
clocks = <&clks IMX6SX_CLK_LCDIF1_PIX>,
<&clks IMX6SX_CLK_LCDIF_APB>,
<&clks IMX6SX_CLK_DISPLAY_AXI>;
clock-names = "pix", "axi", "disp_axi";
port {
parallel_out: endpoint {
remote-endpoint = <&panel_in_parallel>;
};
};
};
Deprecated bindings:
====================
Required properties:
- compatible: Should be "fsl,imx23-lcdif" for i.MX23.
Should be "fsl,imx28-lcdif" for i.MX28.
- reg: Address and length of the register set for LCDIF
- interrupts: Should contain LCDIF interrupts
- display: phandle to display node (see below for details)
