The display controller is a pci device, its PCI vendor id is 0x0014
its PCI device id is 0x7a06.
1) In order to let the driver to know which chip the DC is contained
in, the compatible string of the display controller is updated
according to the chip's name.
2) Add display controller device node for ls2k1000 SoC

Shouldn't the node name just be "display", according to the section 2.2.2
of the DT spec?
lcd-controller, led-controller. As I understood from the bindings, this
is not physical device displaying something (like a panel) but rather a
device controlling such panel. Therefore display-controller feels
appropriate.
