From: Fu Wei <fu.wei@linaro.org>

This patch defines pr_fmt(fmt) for all pr_* functions,
then the pr_* doesn't need to add "arch_timer:" everytime.

According to the suggestion from checkpatch.pl:
(1) delete some Blank Spaces in arch_timer_banner;
(2) delete a redundant Tab in a bland line of arch_timer_init(void)

No functional change.
