wifi/pc: add rtlwifi driver

Due to lacking hardware access the driver was test with one RTL8188EE based device, namely [10ec:8179] (rev 01), only. As the access to the PCI config space is restricted the driver loads the non power-saving FW and the driver port is therefor only tested with that. The accesses are documented should we choose to support them one way or another later on. The 'wifi.run' run script as well as Sculpt served as testing ground where the driver worked fine so far. Fixes #4714.
