Subject: [PATCH 2/2] irq_domain: fix formatting of chip data pointer in virq_debug_show()

On 32-bit machines reading the /sys/kernel/debug/irq_domain_mapping file
outputs following:

virq   hwirq    chip name        chip data           domain name
    9  0x00000  IO-APIC          0x        c175a0f8  none
   10  0x00000  IO-APIC          0x        c175a108  none
   11  0x00000  IO-APIC          0x        c175a118  none
...

which looks a bit funny. Fix that with filling the gap with zeroes instead
of spaces.
