For driver debugfs, debugfs_remove_recursive() is called which is not
needed as it is already done in ASoC core debugfs. And a device managed
memory need not be freed explicitly as device core frees it up. So
remove unnecessary skl_debugfs_exit().

The MCLK for DA7219 does not change in this platform, but is
currently being configured everytime as part of the platform_clock
event handler for DAPM. The upshot of this is that we have
unnecessary calls to this function, and it also means that if
a stream hasn't yet been started, DA7219 driver does not have the
correct MCLK rates programmed and so the HP detection feature does
not operate as expected.

This patch rectifies this issue by moving the sysclk call to
codec_init function so it's only called once at initialisation.

With this patch, the dma buffer size is fetched from topology binary. This

Now that we can configure DSP dma buffer size, the device can support deep

which helps in power reduction.

In commit 9a075265 ("ASoC: Intel: sst: Remove unused function
sst_restore_shim64()"), we deleted the sst_restore_shim64() since it
was never used.  ...but a quick look at the code shows that we should
also be able to remove the sst_save_shim64() function and the
structure members we were storing data in.

Once we delete sst_save_shim64() there are no longer any users of the
'sst_shim_regs64' structure.  That means we can delete it completely
and also avoid allocating memory for it.  This saves a whopping 136
bytes of devm allocated memory.  We also get the nice benefit of
avoiding an error path in the init code.

Note that the saving code that we're removing (and the comments
talking about how important it is to do the save) has been around
since commit 336cfbb0 ("ASoC: Intel: mrfld- add ACPI module").

In SKL+ platforms, all IPC commands are serialised, i.e. the driver sends
a new IPC to DSP, only after receiving a reply from the firmware for the
current IPC.

Hence it seems apparent that there is only a single modifier of the IPC RX
List. However, during an IPC timeout case in a multithreaded environment,
there is a possibility of the list element being deleted two times if not
properly protected.

So, use spin lock save/restore to prevent rx_list corruption.
