FYI this is missing "system/memory.h" which is indirectly included,
otherwise when refactoring unrelated generic headers I get:
include/hw/uefi/var-service.h:50:39: error: field has incomplete type
'MemoryRegion' (aka 'struct MemoryRegion')
50 | MemoryRegion mr;
| ^
include/qemu/typedefs.h:68:16: note: forward declaration of 'struct
MemoryRegion'
68 | typedef struct MemoryRegion MemoryRegion;
| ^
No need to post a fix, I'll with my refactor.
