[PATCH 6/6] pwm: imx: Introduce "polarity_supported" flag to PWMv2 driver

[Lukasz Majewski]

The need for set_polarity() function has been removed by implementing
PWM atomic support (apply() callback).

To indicate that the PWMv2 supports polarity inversion, new flag -
"polarity_supported" has been introduced.
