For debug, the kernel debugfs mechanism is available. We can add various
debug options for driver like module configuration read, firmware register
read etc.

This patch adds debugfs as a child to asoc plaform component and caller is
added for skylake driver to do init and cleanup of debugfs.

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

SKL driver needs to instantiate pipelines and modules in the DSP.
The topology in the DSP is modelled as DAPM graph with a PGA
representing a module instance and mixer representing a pipeline
for a group of modules along with the mixer itself.

Here we start adding building block for handling these. We add
resource checks (memory/compute) for pipelines, find the modules
in a pipeline, init modules in a pipe and lastly bind/unbind
modules in a pipe These will be used by pipe event handlers in
subsequent patches

This helper function will be used by the Skylake driver for dsp and
ipc initialization if processing pipe capability is supported.

The Non-HD Audio Endpoint Description table contains the link
configuration information for the DSP. This is specific to Non HDA
links only, like I2s and PDM

Skylake driver will use NHLT table to retrieve the configuration based
on the link type, format, channel and rate. This configuration is
passed to DSP FW

This adds the dsp and ipc initialization for the Skylake platform.
It also requests firmware and uses code loader dma to load it.
