pwm: stm32: Use the right CCxNP bit in stm32_pwm_enable()
The pwm devices for a pwm_chip are numbered starting at 0, the first hw
channel however has the number 1. While introducing a parametrised macro
to simplify register bit usage and making that offset explicit, one of
the usages was converted wrongly. This is fixed here.
