clocksource/drivers/timer-ti-dm: Use of_address_to_resource()
Replace of_get_address() and of_translate_address() calls with single call to of_address_to_resource(). Signed-off-by: Rob Herring <robh@kernel.org> Signed-off-by: Daniel Lezcano <daniel.lezcano@linaro.org> Link: https://lore.kernel.org/r/20230319163220.226273-1-robh@kernel.org
