Subject: [RFC PATCH 4/4] timer-ti-dm: Fix omap_dm_timer_of_set_source()

With the move to clocksource, the omap_dm_timer_of_set_source() broke
because the "fclk" clock is now defined in the DT.
The omap_dm_timer_of_set_source() was using the first clock declared in the
timer node, but now this clock must be named as "src" and clk_get() use
"src" as clock name to permit specifiying the parent clock of the timer "fclk".
