The original wm_adsp2_early_event took an additional frequency
argument for clocking control so could not be used directly as a
DAPM callback. But this setup could equally be done by the codec
driver function wrapping wm_adsp2_early event. In preparation
for adding support for new core types wm_adsp2_set_dspclk has
been exported, and the freq argument removed so that it can
be used directly as a DAPM callback.

The current code is not setting the compressed IRQ as a wake
source. Normally this doesn't cause any issues as the CODEC
IRQ is set as a wake source by the jack detection code and the
CODEC only produces a single IRQ line. However if the system
is not using jack detection the compressed audio IRQ should
still function as a wake source, as such directly set the
compressed audio IRQ as a wake source.

As requirements to bring up audio paths are continuous getting tighter
and the DSP download to most ADSP devices happens over an external bus
it can become an important factor in the path bring up time. As such
sometimes it is a reasonable trade off to download the firmware ahead of
when it will be required and take a small hit on power consumption for
keeping the core powered up.
This "preloading" adds an additional control for each DSP core "DSPx
Preload Switch" that when set to true will power up the DSP core and
download the firmware currently selected in the "DSPx Firmware" control.
Whilst the core is preloaded the current firmware can not be changed and
the CODEC will be kept powered up and SYSCLK held on. Although future
improvements may allow the SYSCLK to be powered down as well because
the hardware only requires SYSCLK whilst the download is actually taking
place, but this is not covered in this series.

As the compressed ops run on the platform side of things we should
really access the driver data through the platform pointer rather than
the CODEC pointer. As the compressed DAIs in our systems always connect
our CODEC to our platform this has never been an issue, but should still
be corrected. Additionally it clears the way for future core refactoring
work.

Currently SYSCLK is attached to every compressed DAI as this follows the
pattern of attaching clocks to the chips inputs and outputs, however, it is
really the DSP that requires the clock here. As firmware download can be a
significant part of the path startup time for these devices occasionally it
would be desirable to download the firmware in advance of the path being
brought up.
To help facilitate this early firmware loading this patch attaches the
SYSCLK to the DSP preloader widget. This also saves us adding a new route
to SYSCLK every time a new compressed DAI is created.

The two clock domains are enabled based on each input and output of the
chip being connected to its respective clock domain. The ASRC however
can bridge the two domains and as such can function as an input/output
to either domain. The hardware also requires that both clocks are
enabled before the ASRC is. Ensure these constraints by linking the
ASRCs to both SYSCLK and ASYNCCLK.
