This can help a user understand why -global was ignored.
For example: with "-vga cirrus"; "-global vga.vgamem_mb=16" is just
ignored when "-global cirrus-vga.vgamem_mb=16" is not.
This is currently clear when the wrong property is provided:
out/x86_64-softmmu/qemu-system-x86_64 -global cirrus-vga.vram_size_mb=16
-monitor pty -vga cirrus
char device redirected to /dev/pts/20 (label compat_monitor0)
qemu-system-x86_64: Property '.vram_size_mb' not found
Aborted (core dumped)
vs
out/x86_64-softmmu/qemu-system-x86_64 -global vga.vram_size_mb=16 -monitor pty
-vga cirrus
char device redirected to /dev/pts/20 (label compat_monitor0)
