William Wu 83c7532f4f usb: gadget: f_uvc: support uvc and adb use independently 
If we use usb gadget as uvc and adb composite function,
the adb will be disconnected if the uvc camera apk is
closed. I can reproduce this issue by the following steps
on rk3399/rk3288 platforms.

1. Set usb gadget as uvc and adb composite function,
   and open uvc camera apk on rk3399/rk3288 platforms.
2. Connect usb to PC, and use adb shell;
3. Close the uvc camera apk;

And then, the adb will also be disconnected. It's because
that when close the uvc camera apk, the userspace calls
v4l2_release -> uvc_v4l2_release -> uvc_function_disconnect
-> usb_gadget_deactivate -> usb_gadget_disconnect ->
pullup(gadget, 0), this cause usb controller disconnect the
usb connection.

This patch adds a uvc_enabled flag to indicate that usb
is connected, don't call pullup(gadget, 0) to disconnet
usb if we only close uvc camera apk but not plug out usb
cable.
