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.
