6.6-stable review patch. If anyone has any objections, please let me know.

From: Huacai Chen chenhuacai@loongson.cn
commit bf3fa8f232a1eec8d7b88dcd9e925e60f04f018d upstream.
Loongson-2K3000 has a new PCI ID (0x7a46) for its display controller, Add it for pci_fixup_vgadev() since we prefer a discrete graphics card as default boot device if present.
