[PATCHv2 2/9] arm: perf: add missing pr_info newlines

[mark.rutland@arm.com (Mark Rutland)]

Most of the pr_info format strings in perf_event_cpu.c are missing
newlines. Currently we get away with this as the format strings for
subsequent calls to printk (including all pr_* calls) begin with a log
prefix, and the printk core adds the omitted newline for this case.
While generates the output we expect, we probably should not rely on the
format of successive printk calls in order to get legible output.

This patch adds the missing newlines to pr_info format strings in
perf_event_cpu.c, making them consistent with the format strings for
other pr_info, warn, and pr_err calls, and preventing potentially
illegible output if the next printk/pr_* format string doesn't begin
with a log prefix.
