[PATCH v5 0/4] kdb code refactoring

[Sumit Garg]

Some more kdb code refactoring related to:
- Removal of redundant kdb_register_flags().
- Simplification of kdb defcmd macro logic.

Tested with kgdbtest on arm64, doesn't show any regressions.

Changes in v5:
- Incorporated minor comments from Doug.
- Added Doug's review tag.

Changes in v4:
- Split rename of "defcmd_set" to "kdb_macro" as a separate patch.
- Incorporated misc. comments from Doug.
- Added a patch that removes redundant prefix "cmd_" from name of
  members of struct kdbtab_t.

Changes in v3:
- Split patch into 2 for ease of review.
- Get rid of kdb_register_flags() completely via switching all user to
  register pre-allocated kdb commands.

Changes in v2:
- Define new structs: kdb_macro_t and kdb_macro_cmd_t instead of
  modifying existing kdb command struct and struct kdb_subcmd.
- Reword commit message.
