ASoC: Convert WM8994 to use soc-cache.c cache functions
In the process we convert the driver to read registers one at a time when initialising the cache. This has the effect of working around limitations in the sizes of I2C transactions which can be done by some CPUs. Due to the sparseness of the register map the overhead from this should be minimual unless I2C transactions are very expensive to start.
