ASoC: compress: add config item for soc-compress to make it compiled only when needed
We don't always need soc-compress in soc, here add a config item SND_SOC_COMPRESS, when nobody select it, the soc-compress will not be compiled. Here also change Kconfig to 'select SND_SOC_COMPRESS' for drivers that needed soc-compress. Signed-off-by: Jie Yang <yang.jie@intel.com> Signed-off-by: Mark Brown <broonie@kernel.org>
