ASoC: adsp: Add ADSP base support
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. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
