pwm: atmel-hlcdc: Fix default PWM polarity

Browse source 
The PWM device exposed by the HLCDC IP is configured with an inverted
polarity by default. Registering the PWM chip with the normal polarity
was not a problem before commit 42e8992c58d4 ("pwm: Add core
infrastructure to allow atomic updates") because the ->set_polarity()
hook was called no matter the current polarity state, but this is no longer
the case.
