The DSP can have more than one cores. In that case the secondary
core has to be managed by the driver. This patch adds the changes
to driver infrastructure to support multiple core.

A new object skl_dsp_cores is introduced to support multiple
core. Helpers skl_dsp_get_core() skl_dsp_put_core() help to
managed the cores.

Many of the power_up/down and DSP APIs take additional argument
of core_id. The primary core, 0 is always powered up first and
then on demand second core.

Broxton needs to send Purge firmware IPC to DSP before downloading the
firmware. The DMA id needs to be updated for that.

While at it also update Broxton boot sequence to send purge request after
power up and before yanking off reset.

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
read these module params.

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

Broxton DSP is mostly similar to Skylake one but with subtle
differences like no Code Load DMA and uses HDA DMA for code
loading, DSP D0 and D3 sequences are different.

These changes are comprehended by adding different DSP power up
and down handlers, and new loader ops and also adding prepare and
trigger which HDA DSP DMA requires

A module is loaded when the path consisting the module is opened.
The module binary(ies) is loaded from file system and cached in
kernel memory for future use. This is downloaded to DSP using DMA
and invoking Load module IPCs

This patch adds support for load/unload module IPCs, DMAing
modules and manging the modules
