Dump all the PIC, local APIC and I/O APIC information at the
fs_initcall() level, which is after ACPI (if used) has initialised PCI
information, making the point of invocation consistent across MP-table and
ACPI platforms.  Remove explicit calls to print_IO_APIC() from elsewhere.
Make the interface of all the functions involved consistent between 32-bit
and 64-bit versions and make them all static by default by the means of a
New-and-Improved(TM) __apicdebuginit() macro.

 Note that like print_IO_APIC() all these only output anything if
"apic=debug" has been passed to the kernel through the command line.
