[PATCH v4 3/3] sparc: Implement arch_do_panic

[Mete Durlu <meted@linux.ibm.com>]

Implement sparc specific arch_do_panic() instead of using sparc specific
ifdef sections in vpanic() code.
Reorder arch specific panic handling, sparc's Stop-A messages are now
printed after "end Kernel panic" marker.
