clocksource: clean up parse_pmtmr()
I changed the strict_strtoul() to kstrtouint(). That has the check for UINT_MAX built in to it so the ifdefs can be removed. Also I changed a printk() to pr_info(). Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: John Stultz <john.stultz@linaro.org>
