Subject: [PATCH 2/8] ARM: OMAP2+: timer: Simplify clock event/source name setting

For the OMAPs, we're setting up only one clockevent and clocksource. Further,
for DT boot there's no easy way to get the timer name and currently this is
done in an ugly way by reading a hwmod entry. So let's just set it to a simpler
name like timer_clkev and timer_clksrc.
