usb: gadget: uvc: Replace plain printk() with dev_*()
Adding device context to the kernel log messages make them more useful.
Add new uvcg_* macros based on dev_*() that print both the gadget device
name and the function name.
While at it, remove a commented out printk statement and an unused
printk-based macro.
