[PATCH v7 2/5] drivers: pwm: bcm-kona: Dont set polarity in probe

[Jonathan Richardson <jonathar@broadcom.com>]

From: Arun Ramamurthy <arunrama@broadcom.com>

Omit setting the polarity to normal during probe and instead use the
new pwmchip_add_inversed function to register a PWM chip with default
polarity of inversed for all channels as this is the actual hardware
default.
