[PATCH] irqdomain: let the output of irq number align from left side

[Hui Wang]

Except irq number, the rest columns all align from left side, the
output is ugly as following shows,
irq    hwirq    chip name        chip data   domain name
   29  0x0001d  GIC              0x805e1070  /interrupt-<snip>
   34  0x00022  GIC              0x805e1070  /interrupt-<snip>

After applying the fix, the output like that,
irq    hwirq    chip name        chip data   domain name
29     0x0001d  GIC              0x805e1070  /interrupt-<snip>
34     0x00022  GIC              0x805e1070  /interrupt-<snip>

This is a trivial output alignment fix, i don't know if Grant
still maintain the irqdomain subsystem, Cced to Mark for a
backup.

I prefer numbers to be right aligned, because that makes numbers with
different numbers of digits easier to read.
