MLK-14524: dma: Fix division by zero

The audio driver is initialized by preparing a DMA slave channel using 0's
as parameters in sdma_prep_dma_cyclic function. This would lead to a
division by zero, since period_len is used as a divisor.
Used the code from 4.1 to fix this, where the division is made only for
non HDMI peripheral types.
