[PATCH 3/8] ARM i.MX timer: request correct clock

[s.hauer@pengutronix.de (Sascha Hauer)]

We used to pass the timer clock directly to mxc_timer_init. We
should instead request the correct clock. This is an intermediate
step: For now we request the clock in the timer code when NULL
is passed as clock.
