clk: pwm: Let .get_duty_cycle() return the real duty cycle 



pwm_get_state() returns the last requested pwm_state which might differ
from what the lowlevel PWM driver actually implemented. For the purpose
of .get_duty_cycle() the latter is the more interesting info, so use
that to determine the output parameter.
