virtio-gpu-gl-pci not working with arm/aarch64
Description of problem:
Since migration to using virtio-gpu-gl-pci instead of virtio-gpu-pci (commit 17cdac0b51bc4ad7a68c3e5e0b1718729b74d512, used git-bisect to find the problem) my arm guests fail to load. If I use -device virtio-gpu-gl-pci, I don't get any image on the virtual guest screen. If I use -device virtio-gpu-pci, I can boot the guest and get the image, but GL acceleration is not working. Changing sdl to gtk doesn't help.
Steps to reproduce:
1. Download debian netinstall boot iso for arm (https://cdimage.debian.org/debian-cd/current/armhf/iso-cd/debian-11.4.0-armhf-netinst.iso)
2. Copy edk2-arm-code.fd and edk2-arm-vars.fd files from build dir.
3. Run command line ```qemu-system-arm -machine virt -m 512 -cdrom debian.iso -device virtio-gpu-gl-pci -display sdl,gl=on,show-cursor=on -pflash edk2-arm-code.fd -pflash edk2-arm-vars.fd```, get a black virtual screen.
4. Run command line ```qemu-system-arm -machine virt -m 512 -cdrom debian.iso -device virtio-gpu-pci -display sdl,gl=on,show-cursor=on -pflash edk2-arm-code.fd -pflash edk2-arm-vars.fd```, get an image on the virtual screen.
Additional information:
I have an x86_64 guest which uses virgl, and it runs fine after 17cdac0b51bc4ad7a68c3e5e0b1718729b74d512 with only changing virtio-gpu-pci to virtio-gpu-gl-pci
