Now that all users of old copy and silence ops have been converted to
the new PCM ops, the old stuff can be retired and go away.

Replace the copy and the silence ops with the new PCM ops.
In AC97 and I2S-TDM mode, we need to convert back to frames, but
otherwise the conversion is pretty straightforward.

For supporting the explicit in-kernel copy of PCM buffer data, and
also for further code refactoring, three new PCM ops, copy_user,
copy_kernel and fill_silence, are introduced. The old copy and
silence ops will be deprecated and removed later once when all callers
are converted.
The copy_kernel ops is the new one, and it's supposed to transfer the
PCM data from the given kernel buffer to the hardware ring-buffer (or
vice-versa depending on the stream direction), while the copy_user ops
is equivalent with the former copy ops, to transfer the data from the
user-space buffer.
The major difference of the new copy_* and fill_silence ops from the
previous ops is that the new ops take bytes instead of frames for size
and position arguments. It has two merits: first, it allows the
callback implementation often simpler (just call directly memcpy() &
co), and second, it may unify the implementations of both interleaved
and non-interleaved cases, as we'll see in the later patch.
As of this stage, copy_kernel ops isn't referred yet, but only
copy_user is used.

The previous commit [63691587f7b0: ALSA: hda - Apply dual-codec quirk
for MSI Z270-Gaming mobo] attempted to apply the existing dual-codec
quirk for a MSI mobo. But it turned out that this isn't applied
properly due to the MSI-vendor quirk before this entry. I overlooked
such two MSI entries just because they were put in the wrong position,
although we have a list ordered by PCI SSID numbers.
This patch fixes it by rearranging the unordered entries.

This reverts commit 89b593c30e83 ("ALSA: usb-audio: purge needless
variable length array"). The patch turned out to cause a severe
regression, triggering an Oops at snd_usb_ctl_msg(). It was overseen
that snd_usb_ctl_msg() writes back the response to the given buffer,
while the patch changed it to a read-only const buffer. (One should
always double-check when an extra pointer cast is present...)
As a simple fix, just revert the affected commit. It was merely a
cleanup. Although it brings VLA again, it's clearer as a fix. We'll
address the VLA later in another patch.

different style of DT today. Now ALSA SoC supports simple-card driver
for generic/simple sound card, and we have simple-scu-card driver

In the future, V4L2 / ALSA will support HDMI, and then, DT bindings
between V4L2 / ALSA should be merged.

The audio parameter setup in zx_i2s_hw_params() works fine with 32-bit
samples, but for 16-bit ones, all we can hear is harsh noises.
As suggested by vendor driver code, DMA burst size and TS width should
always be 32 bits, no matter audio sample is 16-bit or 32-bit.
Follow the suggestion above to fix the harsh noise issue seen with
16-bit audio samples.

Although the ack callback is supposed to be called at each appl_ptr or
hw_ptr update, we missed a few opportunities: namely, forward, rewind
and sync_ptr.
Formerly calling ack at rewind may have leaded to unexpected results
due to the forgotten negative appl_ptr update in indirect-PCM helper,
which is the major user of the PCM ack callback. But now we fixed
this oversights, thus we can call ack callback safely even at rewind
callback -- of course with the proper handling of the error from the
callback.
This patch adds the calls of ack callback in the places mentioned in
the above.

In design of ALSA pcm core, 'struct snd_pcm_ops.copy' is expected to
copy PCM frames, according to frame alignment on intermediate buffer for
userspace and dedicated buffer for data transmission. In this callback,
value of 'channel' argument depends on the frame alignment, which drivers
registers to runtime of PCM substream. When target devices can handle
non-interleaved buffer, this value has positive value, otherwise negative.
ALSA driver for PCM component of EMU8000 chip is programmed with local
macro to switch the frame alignment. The 'copy' operation in
non-interleaved side has evaluation of the 'channel' argument (actually
it's 'voice' argument). This is useless.
This commit remove the evaluation.
[tiwai: the negative channel argument was the inheritance from the old
code where -1 was meant for interleaved mode. The mix-up was dropped
meanwhile, thus it's correct to assume that we receive no longer -1
there, and it's safe to cleanup the relevant code.
Also, voice=0 for channel==1 is trivial, and it can be dropped, too.]

DesignWare HDMI driver (= dw-hdmi) is supporting HDMI sound, and its
probe function was calling sound binding function multiple times as
same HDMI device different port.
Because of this behavior, commit 9731f82d601 ("ASoC: hdmi-codec: enable
multi probe for ...") was added for multi detection case.
But, this DesignWare HDMI detection/bind code was exchanged/adjusted by
commit 69497eb9234 ("drm: bridge: dw-hdmi: Implement DRM bridge...").
Now, all DesignWare HDMI sound ports are detected as 1 bindng function.
Because of this, hdmi-codec multi detection support is no longer needed.
Thus, this patch removes
commit 9731f82d601 ("ASoC: hdmi-codec: enable multi probe for ..."),
and its related
commit 340327a62c4 ("ASoC: hdmi-codec: Fix hdmi_of_xlate_dai_name...")
