staging: r8712u: Add the new driver to the mainline kernel
This code is for a completely new version of the Realtek 8192 USB devices such as the D-Link DWA-130. The Realtek code, which was originally for Linux, Windows XP and Windows CE, has been stripped of all code not needed for Linux. In addition, only one additional configuration variable, which enables AP mode, remains.
