pwm: hibvt: Explicitly set .polarity in .get_state()

Browse Source 
[ Upstream commit 6f57937980 ]

The driver only both polarities. Complete the implementation of
.get_state() by setting .polarity according to the configured hardware
state.

Fixes: d09f008108 ("pwm: Add PWM driver for HiSilicon BVT SOCs")
