powerpc: Allow debugging of LMBs with lmb=debug

The lmb debugging can be turned on at boottime with lmb=debug on the
command line. However on powerpc that doesn't work, because we don't
necessarily call lmb_dump_all().

So always call lmb_dump_all() after lmb_analyze(), no output is
generated unless lmb=debug is found on the command line.
