From: suijingfeng <suijingfeng@loongson.cn>

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
