This change adds snapshot of usb audio qmi service related files.
A remote entity communicates with usb audio qmi server to enable
or disable particular audio stream on enumerated usb audio device.
This offloads ISOC data transfer operations to remote entity and
allows apps processor to go to power collapse more frequently for
better power saving.
This snapshot was taken as of msm-4.19 commit 3ecc1a5c8726 ("sound:
usb: Don't bail out if qmi_send_indication fails"). In addition,
several updates were made for the current kernel to be compatible
with the GKI ABI, such as making direct calls to APIs exported by
the XHCI driver as well as other minor checkpatch fixes.
