It can be useful for debugging purposes to see at what point the DSP has
powered down, so add a message to inform us of this.

Move the start of booting the DSP to earlier in the DAPM process, and
move the final starting of the DSP to later in the DAPM process. This
allows us to overlap some of the processing with other components of the
system being brought up.

This will allow a marginal speed improvement when used with a bus that
supports async I/O by reducing the amount of context thrashing between
writes, allowing the bus to be more fully utilised.

When locating the memory region relating to a coefficient block written
through a bin file we keep processing the list of regions even after we
have found the region we require. This patch adds a break, so we don't
process redundant list items.

This patch does:
- Move the sanity check with WARN_ON() in wm_adsp_region_to_reg() and
  remove the checks in the callers,
- Fix wrong WARN_ON() usages, replaced with WARN(),
- Fix unreachable or wrong BUG_ON() usages and replace with WARN_ON().

No need to hold on to the `codec' pointer.  We can use the `dsp'

Rename `dirty' to `set' as it is a bit more descriptive.  A set
control is any control that has been set by the user.  We need to ensure
that everytime we boot the DSP we sync out any controls that were
set.

We could at some point start keeping track of the default values of
the controls to suppress some of the device I/O.

Since ASoC does not yet really have the framework features needed to
support propagating sample rates through the device well yet implement
basic support for the ISRCs equivalent to that we currently have for the

in addition to the main audio rate, these being the primary use cases.
