Mostly revert "qemu-help: Sort devices by logical functionality"
This reverts most of commit 3d1237fb2ab4edb926c717767bb5e31d6053a7c5.
The commit claims to sort the output of "-device help" "by
functionality rather than alphabetical". Issues:
* The output was unsorted before, not alphabetically sorted.
Misleading, but harmless enough.
* The commit doesn't just sort the output of "-device help" as it
claims, it adds categories to each line of "-device help", and it
prints devices once per category. In particular, devices without a
category aren't shown anymore. Maybe such devices should not exist,
but they do. Regression.
* Categories are also added to the output of "info qdm". Silent
change, not nice. Output remains unsorted, unlike "-device help".
I'm going to reimplement the feature we actually want, without the
warts. Reverting the flawed commit first should make it easier to
review. However, I can't revert it completely, since DeviceClass
member categories has been put to use. So leave that part in.
