Revision one of the file format includes new algorithm and coefficient
blocks which provide additional information about the controls exported
by the firmware. This patch updates the processing to handle this
version of the file format. Note that whilst this version of the format
adds support for specifying a name for the control through the firmware
file this has not been used and to keep compatibility with existing
deployments no changes to the firmware control naming are made by this
patch.

We have wm_adsp_region, wm_adsp_alg_region, and wmfw_region, the
variables for which are all frequently called region, this can get quite
confusing when reviewing the code especially given some functions are
quite long. Consistently use mem for wm_adsp_regions, alg_region for
wm_adsp_alg_region and region for wmfw_region.
Additionally, we use a mix of adsp and dsp for pointers to the wm_adsp
structure standardise this on dsp.
Finally, we use algs to refer to the number of algorithms quite
frequently, change this to the more descriptive n_algs.

Implement support for a new revision of the coefficeint file format for
ADSP cores.
Since coefficient file format 0 has not been widely deployed and is very
unlikely to ever be used with this driver code support for it has been
removed.

Many current Wolfson devices feature DSPs based around an architecture
known as ADSP. Since there is a lot of commonality in the system
integration of these devices a common library will be used to provide
support for them.
This version provides equivalent support for ADSP1 to that currently
included in the WM2200 driver.

Allow a coefficient set provided using the Wolfson callibration tools to
be provided along with the firmware files. Currently only coefficient
files which configure absolute register addresses are supported.
