schedule: zephyr_dma_domain: Do not use a registered channel

Current implementation only checks if a channel is used with
current interrupt. But that channel might have been registered
with another interrupt earlier.

So, we need a way to skip channels already used. For this, we iterate
over all registered interrupts and check existing registered channels.

This fixes scenarios where running:

$ arecord -Dhw:0,0 -f S32 -c 2 -r 48000 -t raw |
aplay -Dhw:0,0 -f S32_LE -c 2 -r 48000

will result in an I/O error.

topology: imx: fix tdm slot width value

Set correct TDM slot width to 32 bits.

The error has been discovered after commit
0ba64e98ec7d ("SAI: use topology params").
We start using the tdm_slot_width from topology,
rather than hardcoded in code.

drivers: imx: Select DONE bit from software

With multi-fifo we need to enable done bit from software
as we have multiple fifos.

For this we make use of sw_done_sel configurations bits and
write proper bits into SDMA_DONE0 register.

For more information see `SDMA DONE0 Configuration
(SDMAARMx_DONE0_CONFIG)` SDMA register from i.MX8 reference manual.

drivers: sdma: Set watermark level for PDM

In order to enable PDM we need to use Multi-fifo support
and mcu_2_sai RAM script.

This script defines watermark level as follows:

r7 = Watermark
    bit0~11: watermark level(wml*fifo_number)
    bit15~12: to do-fifo number
    bit16~19: fifo offset
    bit27~24: sw done selector
    bit28~31: # audio channels in one frame, 0: 1 channel,1: 2 channels
    bit23: sw done enabled

Configuration parameters should come from DAI (PDM in our specific case)
but there is no easy way to forward such information so we just make
use of some default configuration, 4 fifos, 1 channel per fifo, sw done
enabled.
