2cfb45188a ARM i.MX: remove now unnecessary argument from mxc_timer_init 
As the timer code now does a clk_get to get its clock we don't
need the struct clk argument anymore.
This also changes the alternative EPIT timer to do a clk_get.

509e1f0fd7 ARM: mxc: update clock source registration 
In d7e81c2 (clocksource: Add clocksource_register_hz/khz interface) new
interfaces were added which simplify (and optimize) the selection of the
divisor shift/mult constants.  Switch over to using this new interface.
