[PATCH] ARM: smp: Always separate IPI labels from counters

[xuchenchen]

From: xuchenchen <xuchenchen@xxxxxxxxxx>

The ARM IPI lines in /proc/interrupts print the IPI label separately
from the per-CPU counters. The first counter is printed with "%10u",
which only provides a leading space while the value is less than ten
digits.

Once the counter reaches ten digits, the output can become:

  IPI0:1234129290 ...

Keep a fixed separator after the IPI label so the first counter is
always separated from the label, matching the arm64 output format.
