usb: gadget: Add snapshot of CCID function driver

This USB CCID function driver will be a transport layer between the
userspace CCID component and the Windows Host. Data and control
commands from the Windows Host will be sent to the userspace component
and vice-versa. This snapshot is taken as of msm-4.19 commit 104eef6e1fe8
("platform: msm: Remove unused local count variable").
