Linus Walleij 5745067177 drm/pl111: Enable device-specific assigned memory 
The Versatile Express has 8 MB of dedicated video RAM (VRAM)
on the motherboard, which is what we should be using for the
PL111 if available. On this platform, the memory backplane
is constructed so that only this memory will work properly
with the CLCD on the motherboard, using any other memory
area just gives random snow on the display.

The CA9 Versatile Express also has a PL111 instance on its
core tile that can address all memory, and this does not
have the restriction.

The memory is assigned to the device using the memory-region
device tree property and a "shared-dma-pool" reserved
memory pool like this:

reserved-memory {
        #address-cells = <1>;
        #size-cells = <1>;
        ranges;

        vram: vram@48000000 {
                compatible = "shared-dma-pool";
                reg = <0x48000000 0x00800000>;
                no-map;
        };
};

clcd@1f000 {
        compatible = "arm,pl111", "arm,primecell";
	(...)
        memory-region = <&vram>;
}·;
