ASoC: msm: add soc audio snd virtualization support 



Add soc audio sound card SND_SOC_MSM8996_VM for
virtualization support.
The virtualized audio snd soc is based on legacy
soc msm8996, removing dependency on ARCH_MSM8996
and various soc codec/slimbus and hwdep driver as
well as DTS/SRS PP features.
