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.
