drivers/clocksource/timer-ti-dm: Don't call clk_get_rate() in stop function
[ Upstream commit 12590d4d0e331d3cb9e6b3494515cd61c8a6624e ]
clk_get_rate() might sleep, and that prevents dm-timer based PWM from being
used from atomic context.
Fix that by getting fclk rate in probe() and using a notifier in case rate
changes.
Fixes: af04aa856e93 ("ARM: OMAP: Move dmtimer driver out of plat-omap to drivers under clocksource")
