pwm: Fix regression in pwm-stm32 driver when converting to new waveform support

Browse Source 
Fabrice Gasnier found and fixed a regression I introduced with v6.13-rc1
 when converting the stm32 pwm driver to support the new waveform stuff.
 On some hardware variants this completely broke the driver.
