[PATCH 5/5] sh: Define elfcorehdr_addr in arch dependent section

o Move elfcorehdr_addr definition in arch dependent crash dump file. This is
equivalent to defining elfcorehdr_addr under CONFIG_CRASH_DUMP instead of
CONFIG_PROC_VMCORE. This is needed by is_kdump_kernel() which can be
used irrespective of the fact whether CONFIG_PROC_VMCORE is enabled or
not.

o I don't see sh setup code parsing the command line for elfcorehdr_addr. I
am wondering how does vmcore interface work on sh. Anyway, I am atleast
defining elfcoredhr_addr so that compilation is not broken on sh.
