pwm: cros-ec: Change prototype of helpers to prepare further changes

pwm_chip allocation and registration is about to change. For that the
number of PWM devices must be known earlier in cros_ec_pwm_probe(). So
make cros_ec_pwm_get_duty() and cros_ec_num_pwms() independent of
struct cros_ec_pwm_device which is only available later.
