ASoC: rsnd: fixup clock start checker
commit 4d230d1271 ("ASoC: rsnd: fixup not to call clk_get/set under
non-atomic") fixuped clock start timing. But it exchanged clock start
checker from ssi->usrcnt to ssi->rate.

Current rsnd_ssi_master_clk_start() is called from .prepare,
but some player (for example GStreamer) might calls it many times.
In such case, the checker might returns error even though it was not
error. It should check ssi->usrcnt instead of ssi->rate.
This patch fixup it. Without this patch, GStreamer can't switch
48kHz / 44.1kHz.

ASoC: fix oops w/ for_each_rtd_codec_dai_rollback() macro
A kernel oops happens on an error case (usual missing BE mixer
configuration required by Intel SST driver). Git bisect points to this
macro and an operator precedence issue.

	for (; ((i--) >= 0) && ((dai) = rtd->codec_dais[i]);)

The initial code replaced by this macro was
	while (--i >= 0) {
		codec_dai = rtd->codec_dais[i];

Fix the C operator precedence difference by reverting to pre-decrement

ASoC: wm_adsp: Rename memory fields in wm_adsp_buffer
The wm_adsp_buffer struct is the control header of a circular
buffer used to transfer data from the firmware over the
control interface to an ALSA compressed stream.

The original names of the fields pointing to the data buffer
were based on ADSP2V2 memory layout where they correspond to
{XM, XM, YM}. But this circular buffer could be used on other
types of DSP core that have different memory region types.
Also the names and description of the size fields were not
very clear. The field names and descriptions have been changed
to be generic and not imply any particular memory types.

This patch updates the wm_adsp driver to the new field names.

ASoC: rsnd: enable TDM settings for SSI parent
Some SSIs are sharing each pins (= WS/CLK pin for playback/capture).
Then, SSI parent needs control WS/CLK setting for SSI slave.
In such case, SSI parent needs TDM settings if SSI slave is working as

It can't capture TDM sound without this patch if SSIs were pin sharing.

The STA32x chips feature an XTI clock input that needs to be stable before

handle to the clock. Instead of relying on other parts of the system to
enable the clock, let the codec driver grab a handle itself.

In order to keep existing boards working, clock support is made optional.
