This is needed for the following patches so we can initialize the rest of the hardware timers later on. As with the init_irq calls, there's no need to do cpu_is_omap calls during the timer init as we only care about the major omap generation. This means that we can initialize the sys_timer with the .timer entries alone. Note that for now we just set stubs for the various sys_timer entries that will get populated in a later patch. The following patches will also remove the omap_dm_timer_init calls and change the init for the rest of the hardware timers to happen with an arch_initcall.
