Add snapshot for audio drivers for SDM targets. The code is
migrated from msm-4.9 kernel at the below cutoff -
(74ff856e8d6: "net: ipc_router: Add dynamic enable/disable
wakeup source feature")
This changes are done for new techpack addition
for audio kernel. Migrate all audio kernel drivers
to this techpack.
