This changes davinci_timer_init() so that we pass the clock as a parameter instead of using clk_get(). This is done in preparation for converting to the common clock framework. It removes the requirement that we have to have a clock with con_id of "timer0", which will be good for DT bindings since clock-names = "timer0" doesn't really make sense. Also, drop use of extern in header file since we are touching the definition.
