usb: gadget: Add snapshot of USB GSI function driver 



This change adds USB GSI function driver which provides USB RMNET/RNDIS/
ECM/MBIM/DPL related functionalities with GSI hardware accelerated path.
This snapshot is taken as of msm-4.19 commit 104eef6e1fe8 ("platform:
msm: Remove unused local count variable").

This change also includes some fixups to match the modified API in
dwc3-msm.h.
