Does making these class properties fix

(which is a report that "qemu-system-x86_64 -machine pc-q35,help"
doesn't list these properties) ?
Yes, I can confirm that it does:
Before this series:
$ ./build/qemu-system-x86_64 -M q35,help | grep pflash
$
After this series:
$ ./build/qemu-system-x86_64 -M q35,help | grep pflash
pflash0=<str> - Node name or ID of a block device to use as
a backend
pflash1=<str> - Node name or ID of a block device to use as

ATB,
Mark.
