pwm: Remove wrong implementation details from pwm_ops's documentation

When .get_state() is called is an implementation detail that
implementors and users shouldn't care about and rely on. Additionally
it's wrong, because with PWM_DEBUG enabled it is called more often.

Just drop the wrong statement.
