PDM driver can now be used on nRF54H20. It required an addition of DMM mechanism and minor changes to clock management,
nRF54H20 does not require clock control in case of PDM driver.
Currently, product specification for nRF54H20 PDM does not provide fully correct formula to calculate PDM clock frequency, thus master clock source frequency has to be passed as 8 MHz to ensure proper driver behavior. To be corrected and removed once correct formula is found.
