USB: add Printer Gadget Driver
G_PRINTER: Adds a USB printer gadget driver for use in printer firmware.
This adds a USB printer gadget driver for use in printer firmware.
The printer gadget channels data between the USB host and a userspace
program driving the print engine. The user space program reads and
writes the device file /dev/g_printer to receive or send printer data.
It can use ioctl calls to the device file to get or set printer status.
