[PATCH] i386: apic_printk() used before initialized

Both detect_init_APIC() and init_apic_mappings() it's called from are
invoked early, before the command line has been processed.  Therefore its
meaningless to call apic_printk() from them as that depends on
apic_verbosity which is initialized from the command line.

I could move apic_verbosity initialization to parse_cmdline_early(), but I
think that would be an overkill, the point being we are initerested in
feedback from detect_init_APIC() anyway.  Without that it's hard to tell
what's really going on as it's been the case with the recent report of the
local APIC being non-functional despite the whole setup being apparently
correct.  So I converted these calls to ordinary printk() invocations.  The
init_apic_mappings() are less interesting, so I've made them output at the
debug level.

While at it I've made some obvious nearby formatting clean-up.
