Blackfin: fix command line corruption with DEBUG_DOUBLEFAULT
Commit 6b3087c6 (which introduced Blackfin SMP) broke command line passing when the DEBUG_DOUBLEFAULT config option was enabled. Switch the code to using a scratch register and not R7 which holds the command line. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
