The driver needs two DSP callback, one to set D0i0 (active) and D0i3
(low-power) states.

Add these callbacks in dsp ops and implement them for broxton platforms.

To set the controller in D0i3 mode, the driver needs to set D0i3C
register after DSP is quiesced. Since the D0iX entry/exit is done by IPC,
add this as callback so that it can be invoked from IPC module.

The audio DSP supports intermediate power states between D0 and D3
states. These states are D0i0 and D0i3 states.

Collectively we refer these two states as D0iX states.

To set or wake up from these states, driver also needs to send an IPC "Set D0iX
IPC" before doing anything else.

Add support for this new IPC messages.

The DSP instance creation also loads the firmware on DSPs. For library load
the firmware names come from topology so can't be loaded at object creation.

So split the firmware load and object creation. FW load is now called after
topology init in platform probe.

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 DSP needs retains code loaded during runtime_pm cycles.
But it looses that on suspend cycle, so on resume we need to
download the firmware again.

This is done by adding a new flag and based on flag status, we
download the firmware.

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.

MISCBDCGE is a new register for Misc Backbone clock gate control
which is useful to control while resetting the link and ensuring
controller is in required state so add API to control it

HW recommends that we reset with CGCTL.MISCBDCGE disabled, so add
that while doing init chip and reset sequence.

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
