From: Sui Jingfeng <suijingfeng at loongson.cn>
Currently, the default VGA device selection is not perfect. Potential
problems are:
1) This function is a no-op on non-x86 architectures.
2) It does not take the PCI Bar may get relocated into consideration.
3) It is not effective for the PCI device without a dedicated VRAM Bar.

calling the vga_client_register() function.
