armv7: work around hang in bootblock startup code
broadcom cygnus hangs if we clean caches by dcache_clean_invalidate_all
at bootblock entry point. this change makes startup code call
dcache_invalidate_all instead.
other boards theoretically should not be affected as long as maskrom
does not hand off execution to bootblock with dirty cache.
