Lots of sound drivers were getting module.h via the implicit presence
of it in <linux/device.h> but we are going to clean that up. So
fix up those users now.

It is not used outside this driver so no need to make the symbol global.

snd_pcm_hw_constraint_integer() could return -1, in this case, sst platform is
not opened successfully. However the corresponding close callback isn't able
to be called later on to release these two allocated memories, thus resulting
in memory leak.
This patch moves the check for hardware contraints earlier, thus resolving this
issue.

Use the builtin snd_soc_set_runtime_hwparams() instead of assigning it by

Currently pcm_new() passes in 3 arguments :- card, pcm and DAI.
Refactor this to only pass in 1 argument (i.e. the rtd) since struct rtd contains
card, pcm and DAI along with other members too that are useful too.

module_name will be checked in register_sst_card.
It will fail to register sst card if it's not initialized.

Pulseaudio doesnt work with current driver and it was root caused to absense of
hw_params function and malloc_pages in it.
This patch adds this and allows pa to work fine with these drivers

Few funtions can be modularized in this driver to make them look cleaner
like managing the stream status with locks and filling pcm parameters.
This patch adds helper functions to do the same.

This patch adds the platform driver for mid asoc drivers. This platfrom
driver sends commands to sst dsp engine driver for the dai operations.
For this purpose it depends on intel_sst driver which is currently in
staging tree
