powerpc/irq: use seq_put_decimal_ull_width() for decimal values
On a system with n CPUs and m interrupts, there will be n*m decimal
values yielded via seq_printf(.."%10u "..) which is less efficient
than seq_put_decimal_ull_width(), stress reading /proc/interrupts
indicates ~30% performance improvement with this patch.
