rt2x00: Don't initialize beacon interval to 0 on rt2800 devices
Activating the TBTT interrupt when a beacon interval of 0 is configured
results in an interrupt storm causing the machine to hang. Hence,
initialize the beacon interval to a reasonable default of 100TUs.

rt2x00: Remove set_tim callback from PCI drivers
Using the set_tim callback without managing the DTIM count and the
broad- and multicast buffering in hw, fw or the driver results in wrong
DTIM count values being sent out in beacons. Since all PCI drivers
fetch new beacons periodically and hence get an updated TIM we can just
remove the set_tim callback from these.
The rt2x00 USB drivers don't update the beacon periodically and thus
rely on the set_tim callback to get a correct TIM for beacon
transmission. USB devices still suffer from the DTIM count being wrong
under some circumstances but removing the set_tim callback from these
would cause more harm then good.

Also, add a new driver flag to indicate if a driver has pre tbtt support

Since all rt2x00 PCI drivers use threaded interrupts now we don't need

Use threaded interrupts for all rt2x00 PCI devices.

- Reduce the time we spend in hard irq context
- Use non-atmic mac80211 functions for rx/tx
Furthermore implementing broad- and multicast buffering will be
much easier in process context while maintaining low latency and
updating the beacon just before transmission (pre tbtt interrupt)
can also be done in process context.
