If we're setting the currently applied value for one of the DSP algorithm
configurations we can just skip all the handling as the control set is a
noop. This ensures we do not disrupt a running DSP.

With appropriate firmware the WM8958 can support Virtual Surround Sound or
VSS, widening the stereo audio image for improved user experience. Enable
support for this mode of operation when the appropriate firmware can be
loaded at runtime.

In preparation for the addition of additional WM8958 algorithms
reorganise the code to make it easier to add such support later.

Allow userspace to supply an update to the ROM firmware. The firmware
request is non-blocking so userspace can load the firmware at its
leisure without delaying startup, the driver will begin using the
firmware the next time MBC is started after it has been supplied.

The DSP2 startup requires that the clock be enable so if we've deferred
clock startup we need to defer DSP2 startup

DSP2 on the WM8958 has a default ROM which provides a multi-band
compressor for enhanced performance on mobile devices but can also
support runtime download of alternative firmware. In preparation for
more exploiting this functionality refactor the code to split the
handling of DSP2 into a separate file.
