virtio/virtio-gpu: fbmem should transfer to pa

[terry0012]

Summary

Map the framebuffer memory address to the physical address to resolve the framebuffer issue in qemu with command -device virtio-gpu-pci.

When using the virtio-gpu-pci device, we observed that the virtio-gpu driver does not create the /dev/fb0 node. The reason is that in PCI mode, the framebuffer address needs to be translated to a physical address for proper operation.

Additionally, there is another bug in the current code related to PCI device scanning for the virtio-gpu-pci device. @CV-Bowen will submit a patch to fix it.
