KGDB/KDB fixes and cleanups
 Cleanups
   Remove kdb ssb command - there is no in kernel disassembler to support it
   Remove kdb ll command - Always caused a kernel oops and there were no
       bug reports so no one was using this command
   Use kernel ARRAY_SIZE macro instead of array computations

 Fixes
   Stop oops in kdb if user executes kdb_defcmd with args
   kdb help command truncated text
   ppc64 support for kgdbts
   Add missing kconfig option from original kdb port for dealing with
      catastrophic kernel crashes such that you can reboot automatically
      on continue from kdb
kdb: Remove unhandled ssb command

The 'ssb' command can only be handled when we have a disassembler, to check for
branches, so remove the 'ssb' command for now.
