Indicate to the kernel that the usb gadget is pulled up
by writing to `update_sdp_enum_timeout` sysfs node. Write
to this node will inform the kernel that it can lower the SDP
timeout alarm value which is used to detect an SDP port
vs a DCP.

UVC is a new USB function supported in Android. This CL adds UVC as a
valid function and gives it a new pid of 0x4ee[de]. UVC function is
guarded by the property `ro.usb.uvc.enabled`. When this property is set
to false, UVC won't be considered as a valid gadget function.
Bug: 242344221
Test: Manually tested that the UVC function is successfully configured
