request firmware, strip extended manifest and release library changes
are common to kabylake and APL.

So move these common code to utils to be reused in later patches for
kabylake library load.

Some skl sst context are not dependent of platform and initializing them
independently for each platform can lead to errors. So optimize by
moving them to a helper function and platform specific init code can
call this.

Since modules ids are generated dynamically, we do not know the id
associate with modules in another pipelines. This limits our ability to
tell DSP about neighbouring modules.

So add a table for quick referencing of allocated module ids.

Driver needs to send unique module instance id to firmware while
creating the module and uses this id to communicate with DSP for setting
parameters while audio use case is ongoing.

But, we have upper bound of instance ID. The current IDs are coming from
topology but it doesn't know the upper bound and can't assign unique
id's subject to upper bounds as we can create a big graph but not all
parts running at same time.

This patch adds a 128bit unique id management routines which are built
on top of ffz() for faster implementation. Unfortunately ffz() works on
32bits values, so additional code is added on top of ffz() to create a
128bit unique id.

snd_skl_get_module_info() takes skl_dfw_module as an argument. The users
then updates the topology data, so instead pass skl_module_cfg and let

For additional library parsing, we need to pass firmware to be
loaded and not use the pointer in context. Also, Library module
IDs are combination of library index and module ID in manifest.

So add the additional arguments of firmware and library offset to
snd_skl_parse_uuids().

Module params like module_id and loadable flag can be changed
in the DSP Firmware. These are kept in the firmware manifest
and driver should read these values from this manifest.

So, add support to parse the DSP firmware manifest and

Some upcoming platforms like broxton etc have extended manifest
in firmware binary. This is not required to be downloaded to DSP.
So driver needs to strip this before downloading.

Add a utility function to check if a header exists, and remove it
in that case
