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
commit <2e7ac4ed668> ("Merge "msm: ipa: Fix to add string NULL
terminator"").
