Jarkko Nikula 1f2bd2271a pwm: Allow store 64-bit duty cycle from sysfs interface ...

PWM core was converted to u64 by the commit a9d887dc1c ("pwm: Convert
period and duty cycle to u64") but did not change the duty_cycle_store()
so it will error out if trying to pass a numeric string bigger than
2^32-1.

Fix this by using u64 and kstrtou64() in duty_cycle_store().
