Current comment makes not clear the direction of mclk. Previously, similar
description caused a misunderstanding for bclk_master and fsync_master.

This commit solves the potential confusion the same way it is solved for
bclk_master and fsync_master.

Clock gating parameter is a part of `dai_fmt`. It is supported by
`alsa-lib` when creating a topology binary file, but ignored by kernel
when loading this topology file.

After applying this commit, the clock gating parameter is not ignored any
more. This solution is backwards compatible. The existing behaviour is
not broken, because by default the parameter value is 0 and is ignored.

snd_soc_tplg_hw_config.clock_gated = 0 => no effect
snd_soc_tplg_hw_config.clock_gated = 1 => SND_SOC_DAIFMT_GATED
snd_soc_tplg_hw_config.clock_gated = 2 => SND_SOC_DAIFMT_CONT

For example, the following config, based on
alsa-lib/src/conf/topology/broadwell/broadwell.conf, is now supported:

~~~~
SectionHWConfig."CodecHWConfig" {
        id "1"
        format "I2S"            # physical audio format.
        pm_gate_clocks "true"   # clock can be gated
}

SectionLink."Codec" {

        # used for binding to the physical link
        id "0"

        hw_configs [
                "CodecHWConfig"
        ]

        default_hw_conf_id "1"
}

The values of bclk and fsync are inverted WRT the codec. But the existing
solution already works for Broadwell, see the alsa-lib config:

`alsa-lib/src/conf/topology/broadwell/broadwell.conf`

This commit provides the backwards-compatible solution to fix this misuse.

The freq parameter indicates the physical frequency of an actual

It is waiting udelay(50) x 1024 (= 50ms) for status check

And we shouldn't use udelay() for 50us

Waiting maximum udelay(5) x 1024 (= 5ms) is very enough

commit 4821d914 ("ASoC: rsnd: use dma_sync_single_for_xxx() for
IOMMU") (= v1) which have been already reverted had supported IPMMU
support on rsnd driver.
Because memory allocating timing and DMAEngine access timing were
different, it used continuous memory and called dma map function by
itself.

OTOH, it is using DMA descriptor mode (= DMA cyclic mode), thus, there
was timing conflict between DMA sync/unsync and DMA transfer starting,
and it maked sound noise.

This patch supports IPMMU with coherent memory, and, it uses Audio DMAC
dev for allocating memory by snd_pcm_lib_preallocate_pages_for_all() to
indicate memory area to IPMMU.
One note is that Playback/Capture need each paired Audio DMAC dev.
Because of this, we need to keep each paired Audio DMAC dev when probing,
and use it when allocating each memory for IPMMU.

Current ssi.c is assuming below 2 things to probing HDMI node.
1) remote node is including "hdmi0" or "hdmi1" in node name
2) remote_ep->full_name is including full path name

But, these assumptions are broken by below
1) Node names should not use numerical suffixes
 commit 6b5ac2f1 ("arm64: dts: renesas: r8a7795: Drop bogus HDMI
                       node names suffixes")
2) node full_name no longer include full path name
 commit a7e4cfb0 ("of/fdt: only store the device node basename
                       in full_name")

Because of these reasons, ssi.c can't probe HDMI on current kernel.
This patch probes HDMI0/1 by using its address.
Note is that we need to keep updating for this address for future
generation chip.

Thus, it is assuming Gen2 and Gen3 have compatible, therefore,
there is no RSND_GEN3 and rsnd_is_gen3() macro.
