Subject: [PATCH 4/4] ARC: Use clockevents_config_and_register over clockevents_register_device

From: Uwe Kleine-König <u.kleine-koenig@...gutronix.de>

clockevents_config_and_register is more clever and correct than doing it
by hand; so use it.

[vgupta: fixed build failure due to missing ; in patch]
