[ARM] S3C: Fix scaler1 clock rate information
The pwm-scaler0 and pwm-scaler1 clocks have their .id field set to -1 as they are not referenced to any specific device. However, parts of the pwm-clock code used the .id field to identify which scaler clock was being used. Fix the problem by comparing against the pointer to the clock to identify the scalers.
