ASoC: Intel: Make atom components independent of sst-dsp
With sound/soc/intel/haswell and /baytrail gone, registers left within
sst-dsp header are atom-specific. Relocate these to atom internal header
to make atom truely independent of sound/soc/common processing code.

ASoC: Intel: atom: Fix uninitialized variable compiler warning
GCC 10 gives a "variable might be used uninitialized" warning for the
block variable in sst_prepare_and_post_msg().

This is a false-positive warning, but lets fix it anyways.

bcb46a0e0e sound fixes for 5.2-rc5
you might feel like a deja vu to receive a bulk of changes at rc5,
 and it happens again; we've got a collection of fixes for ASoC.
 Most of fixes are targeted for the newly merged SOF (Sound Open
 Firmware) stuff and the relevant fixes for Intel platforms.
 
 Other than that, there are a few regression fixes for the recent
 ASoC core changes and HD-audio quirk, as well as a couple of
 FireWire fixes and for other ASoC codecs.

ASoC: Intel: sst: fix kmalloc call with wrong flags
When calling kmalloc with GFP_KERNEL in case CONFIG_SLOB is unset,
kmem_cache_alloc_trace is called.

In case CONFIG_TRACING is set, kmem_cache_alloc_trace will ball
slab_alloc, which will call slab_pre_alloc_hook which might_sleep_if.

The context in which it is called in this case, the
intel_sst_interrupt_mrfld, calling a sleeping kmalloc generates a BUG():

61ab0d403b ASoC: Intel: Atom: add a missing star in a memcpy call
In sst_prepare_and_post_msg(), when a response is received in "block",
the following code gets executed:

    *data = kzalloc(block->size, GFP_KERNEL);
    memcpy(data, (void *) block->data, block->size);

The memcpy() call overwrites the content of the *data pointer instead of
filling the newly-allocated memory (which pointer is hold by *data).
Fix this by merging kzalloc+memcpy into a single kmemdup() call.

Thanks Joe Perches for suggesting using kmemdup()
