If the Halo registers are kept in the register cache the
HALO_CORE_RESET bit will be retained as 1 after reset is triggered in
cs_dsp_halo_start_core. This will cause subsequent writes to reset
the core which is not desired. Apart from this bit the rest of the
register bits are cacheable, so for safety sake clear the bit to
ensure the cache is consistent.

The code already has a post_run callback, add a matching pre_run
callback to the client_ops that is called before execution is started.
This callback provides a convenient place for the client code to
set DSP controls or hardware that requires configuration before
the DSP core actually starts execution. Note that placing this callback
before cs_dsp_coeff_sync_controls is important to ensure that any
control values are then correctly synced out to the chip.

The firmware coefficient files contain version information that is
currently ignored by the cs_dsp code. This information specifies which
version of the firmware the coefficient were generated for. Add a check
into the code which prints a warning in the case the coefficient and
firmware differ in version, in many cases this will be ok but it is not
always, so best to let the user know there is a potential issue.

wm_adsp originally provided firmware loading on some audio DSP and was
implemented as an ASoC codec driver. However, the firmware loading now
covers a wider range of DSP cores and peripherals containing them,
beyond just audio. So it needs to be available to non-audio drivers. All
the core firmware loading support has been moved into a new driver
cs_dsp, leaving only the ASoC-specific parts in wm_adsp.
