Revert "MLK-18497-13: ASoC: fsl: dsp: Skip SDRAM section update if
fw is already loaded"
This reverts commit a0cffd9a9299362f2b3a4d24b78a8574b736fdfa.
This is just to avoid reconfigure the edma isr handler in dsp
framework, which should be handled by dsp framework.

On QM the DSP is inside the VPU subsystem while in QXP
it is inside the Audio DMA subsystem. For this reason
there are "subtle" differences.
Introduce new compatible string for QM to help us correctly
configure the DSP depending on the board they run.
dsp_mem_msg structure is shared with the DSP, so by introducing
new member dsp_board_type we can let DSP know on which target it runs.

We must find a way to no longer touch resources after they are
cleand up.
Now, after a stress test we get the following crash:
[ 2156.863772] fsl-dsp 596e8000.dsp: xf_pool_alloc failed
[ 2156.869337] Unable to handle kernel NULL pointer dereference at
virtual address 00000060

[ 2157.182754] [<ffff000008b11b24>] snd_compr_free+0x64/0x98
This happens because:
1) dsp_platform_process work handler waits in a loop for
messages to arrive.
2) when cplay process finishes it cleans up most of the
resources.
3) when another cplay process starts it reinitializes the
resources including queues for example.
4) a message will be generated and kernel will crash because
dsp_platform_process uses the older queues.
A solution for this is to make sure dsp_platform_process work loop
is stopped at cleanup time.
We use is_active state and signal dsp_platform_process handler to
finish because we are on the cleanup path.
While at it replace cancel_work with cancel_work sync to be sure
that work handler ends before going on with the rest of the cleanup.

If the DSP firmware binary is already loaded it is wrong to update
SDRAM located sections because we will overwrite and data stored there.
This makes suspend/resume work.

This will allow DSP driver to create/destroy a client on
DSP audio-framework proxy.
Registering a client on remote DSP proxy means creating
a component.
The implementation is similar with userspace application
proxy implementation.

Memory is allocated to clients from memory pools. A memory pool
allocation is requested to DSP framework via XF_ALLOC command and
freed via XF_FREE.
Memory pool allocation API offers two functions:
* xf_pool_alloc, allocate a number of buffers of given length
* xf_pool_free, free memory area allocated for a pool.
Once a buffer pool is allocated users can handle buffers using the
following API:
* xf_buffer_get(pool), gets a buffer from a pool
* xf_buffer_put(buf), puts back a buffer into its pool

This commit adds 3 new function helpers for sending
messages to DSP framework and waiting for response.
While at it cleanup spaces around struct client fields.

In order to avoid the name problem going forward with
integration with Qcom, Qcom has their own dsp and hifi
is competitor, so the hifi name should not be used in
our code.
So use the name of dsp instead of hifi to fix this
problem.
