75bd90860a ASoC: intel: Use kvzalloc() for suspend buffers
Intel SST driver allocates lots of pages at suspend for saving the
firmware states, and this may occasionally lead to the allocation
error due to the high order, ending up with the suspend failure.

Use kvzalloc() so that it can fall back to vmalloc() gracefully.

98cf2c03b4 ASoC: Intel: sst: Delete sst_shim_regs64; saved regs are never used
In commit 9a075265c6dc ("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 336cfbb05edf ("ASoC: Intel: mrfld- add ACPI module").
