Add PM and RTD3 support to the HSW/BDW PCM driver. The PCM driver will
now save DSP context and then power off the DSP when it's not in use.
DSP power and context is then restored when it's next used.

Current block allocation is tied to block type and requestor type. Make the
allocation more generic by removing the struct module parameter and adding
a generic block allocator structure. Also pass in the list that the blocks
have to be added too in order to remove dependence on block requestor type.

ASoC: Intel: update scratch allocator to use generic block allocator

Update the scratch allocator to use the generic block allocator and calculate
total scratch buffer size.

ASoC: Intel: Add call to calculate offsets internally within the DSP.

A call to calculate internal DSP memory addresses used to allocate persistent
and scartch buffers.

ASoC: Intel: Add runtime module support.

Add support for runtime module objects that can be created for every FW
module that is parsed from the FW file. This gives a 1:N mapping between
the FW module from file and the runtime instantiations of that module.

We also need to make sure we remove every module and runtime module when
we unload the FW.

ASoC: Intel: Add DMA firmware loading support

Add support for DMA to load firmware modules to the DSP memory blocks.
Two DMA engines are supported, DesignWare and Intel MID.

ASoC: Intel: Add runtime module lookup API call

Add an API to allow quick lookup of runtime modules based on ID.

ASoC: Intel: Provide streams with dynamic module information

Remove the hard coded module paramaters and provide each module with
dynamically generated buffer information for scratch and persistent
buffers.

The Intel IOMMU requires that the ACPI device is used to allocate all
DMA memory buffers. This means we need to pass the DMA device pointer into child
component devices that allocate DMA memory.

We also only set the DMA mask for the ACPI device now instead of for each
component device.

While the SHIM register addresses in Baytrail are the same than Haswell and
Broadwell their register size is 64-bit and some bits are different.

We originally thought to request SST audio DSP firmware during the SST
platform driver initialization. However plain request_firmware doesn't
work in driver probe paths if userspace is not ready to handle it. For
instance when drivers are built-in.

Implementing asynchronous firmware request in SST platform driver
initialization complicates code needlessly since it anyway will fail if
firmware is missing.

This is more simple to handle by requesting firmware asynchronously in
sst_acpi_probe() and register SST platform only after firmware is loaded.

Add support for Intel Smart Sound Technology (SST) audio DSPs.
This driver provides the low level IO, reset, boot and IRQ management
for Intel audio DSPs. These files make up  the low level part of the SST
audio driver stack and will be used by many Intel SST cores like
Haswell, Broadwell and Baytrail.

SST DSPs expose a memory mapped region (shim) for config and control.
The shim layout is mostly shared without much modification across cores
and this driver provides a uniform API to access the shim and to enable
basic shim functions. It also provides functionality to abstract some shim
functions for cores with different shim features.
