Subject: [PATCH 1/3] clocksource: em_sti: remove unneeded memset()s

Memory for cs and ced fields in struct em_sti_priv is allocated
by devm_kzalloc() in the beginning of em_sti_probe() so they
don't need to be zeroed one more time in
em_sti_register_clocksource() and in em_sti_register_clockevent().
