Make it so the magic "reset_config" keywords can be provided in any
order. This eliminates needless error paths, and makes it easier
to define things at the right level (adapter, board, target).
It also includes two other behavioral changes:
(1) When "handle_reset_config" sees a parameter error, it
exits without changing anything. This is best viewed
as a bugfix. (Old behavior: restore defaults, even if
they weren't previously active.)
(2) Only the behaviors that were explicitly specified get
changed. (Old behavior: everything else gets reset to
the "default".) So for example you can now specify SRST
drive requirements without saying anything about the
three unrelated topics you previously had to specify.
That second one might cause confusion for any configs that end
up calling "reset_config" twice, so it will deserve to be called
out in the release notes. (There were no such configurations in
the current OpenOCD source tree.)
