rtlwifi: rtl_pci: Start modification for new drivers

Browse Source 
Future patches will move the drivers for RTL8192EE and RTL8821AE
from staging to the regular wireless tree. Here, the necessary features
are added to the PCI driver. Other files are touched due to changes
in the various data structs.
