The imx35 clock driver will use EPIT timer when option CONFIG_MXC_USE_EPIT is enabled. However, initializing timers from clock driver is a workaround solution and causes problem when we move clock drivers into driver/clk. Let's simply drop the EPIT initialization from there. If people really want this EPIT option, EPIT timer driver needs to be reworked to do the initialization in a standard way - use CLOCKSOURCE_OF_DECLARE() with device tree support.
