drivers: pwm: mcux_tpm: allow configuring the clock prescaler

Browse source 
Allow configuring the clock prescaler divider for the NXP Kinetis
Timer/PWM Module (TPM). Setting the prescaler to a lower value
allows for higher resolution for the generated PWM waveforms.
This change is inspired from the pwm_mcux_ftm driver:
