For virtio VGA deivce libvirt will select VIRTIO_VGA firstly rather than
VIRTIO_GPU, VIRTIO_VGA device supports frame buffer however it requires
legacy VGA compatible support. Frame buffer area 0xa0000 -- 0xc0000
conflicts with low memory area 0 -- 0x10000000.
Here remove default support for VIRTIO_VGA device, VIRTIO_GPU is prefered
on LoongArch system. For frame buffer video card support, standard VGA can
be used.
