Mostly revert "qemu-help: Sort devices by logical functionality"
This reverts most of commit 3d1237fb2a.
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.
