x86 I/O APIC: Dump I/O APIC regs in `ioapic.c`

Some southbridges have code in their `lpc.c` files to dump the
    I/O APIC registers.

printk(BIOS_SPEW, "Dumping IOAPIC registers\n");
        for (i=0; i<3; i++) {
                *ioapic_index = i;
                printk(BIOS_SPEW, "  reg 0x%04x:", i);
                reg32 = *ioapic_data;
                printk(BIOS_SPEW, " 0x%08x\n", reg32);
        }

Add similar code to `src/arch/x86/lib/ioapic.c` so all boards using
    the function `set_ioapic_id()` get the debug feature and the other
    boards can be more easily adapted in follow-up patches.
