usb: gadget: uvc: Make bSourceID read/write

Browse source

[ Upstream commit b3c839bd8a ]

At the moment, the UVC function graph is hardcoded IT -> PU -> OT.
To add XU support we need the ability to insert the XU descriptors
into the chain. To facilitate that, make the output terminal's
bSourceID attribute writeable so that we can configure its source.
