arm: vt8500: doc: Add device tree bindings for arch-vt8500 devices Bindings for gpio, interrupt controller, power management controller, timer, realtime clock, serial uart, ehci and uhci controllers and framebuffer controllers used on the arch-vt8500 platform. Framebuffer binding also specifies a 'display' node which is required for determining the lcd panel data. Signed-off-by: Tony Prisk <linux@prisktech.co.nz>

Wondermedia WM8505 Framebuffer
-----------------------------------------------------
Required properties:
- compatible : "wm,wm8505-fb"
- reg : Should contain 1 register ranges(address and length)
video: fb: vt8500: Convert framebuffer drivers to standardized binding Now that a display timing binding is available, convert our almost identical binding to use the standard binding. This patch converts the vt8500 and wm8505 framebuffer drivers and associated dts/dtsi files to use the standard binding as defined in bindings/video/display-timing.txt. There are two side-effects of making this conversion: 1) The fb node should now be in the board file, rather than the soc file as the display-timing node is a child of the fb node. 2) We still require a bits per pixel property to initialize the framebuffer for the different lcd panels. Rather than including this as part of the display timing, it is moved into the framebuffer node. I have also taken the opportunity to alphabetise the includes of each driver to avoid double-ups.
