clocksource/drivers/mxs_timer: Add missing semicolon when DEBUG is defined

clocksource/drivers/mxs_timer: Add missing semicolon when DEBUG is defined

[ Upstream commit 7da390694afbaed8e0f05717a541dfaf1077ba51 ]

When DEBUG is defined this error occurs

drivers/clocksource/mxs_timer.c:138:1: error:
  expected ‘;’ before ‘}’ token

The preceding statement needs a semicolon.
Replace pr_info() with pr_debug() and remove the unneeded ifdef.
