rt2x00: Optimize TX descriptor handling
HT and no-HT rt2x00 devices use a partly different TX descriptor. Optimize the tx desciptor memory layout by putting the PLCP and HT substructs into a union and introduce a new driver flag to decide which TX desciptor format is used by the device. This saves us the expensive PLCP calculation fOr HT devices and the HT descriptor setup on no-HT devices.
