It needs free pcm runtime modules before unloading firmware, here
add hsw_pcm_suspend() to handle this procedure:
suspends firmware ==> frees runtime modules ==> unloads firmware.
This fixes the broadwell module unload failed issue.

Add check runtime module pointers before freeing them, and clear
them to NULL after freed.
With this implemented, we can avoid NULL pointer dereference or
double free errors.

This reverts commit 01f202c7b4.
We shouldn't leave the device as suspended state after module freed,
it is not good to do runtime suspend at driver free, here revert
this fixing, and replace it with the procedure:
suspends firmware ==> frees runtime modules ==> unloads firmware.

This reverts commit 506c148ee5.
We still need this hsw_pcm_free_modules(), we plan to remove the
runtime modules at both fw_unload(D0->D3) and snd_soc_sst_haswell_pcm
module removing.

In haswell-pcm module unloading, we can't free runtime modules
directly, for they may be already freed in runtime suspend.
Here add executing suspend call to unload runtime modules, only
for status not equal to RPM_SUSPEND, to fix broadwell module
removing failed issue.

kbuild robot reports following warning:
"sound/soc/intel/haswell/sst-haswell-ipc.c:2204:1-6:
WARNING: invalid free of devm_ allocated data"
As julia explains to me, the memory allocated with devm_kalloc
is freed automatically on failure of a probe function. So this
kfree should be removed otherwise the double free will be got in
error handler path.

sound/soc/intel/haswell/sst-haswell-ipc.c:646:28-29: WARNING: Use ARRAY_SIZE
Use ARRAY_SIZE instead of dividing sizeof array with sizeof an element
Semantic patch information:
This makes an effort to find cases where ARRAY_SIZE can be used such as
where there is a division of sizeof the array by the sizeof its first
element or by any indexed element or the element type. It replaces the
division of the two sizeofs by ARRAY_SIZE.
