It is desirable to move all clocksource drivers to drivers/clocksource, yet each requires its own initialization function. We'd rather not pollute <linux/> with a header for each function. Instead, create a single of_clksrc_init() function which will determine which clocksource driver to initialize based on device tree. Based on a similar patch for drivers/irqchip by Thomas Petazzoni.
