This adds PIO support back (D'oh!) for PCMCIA devices.
This is a complete rewrite of the old PIO code. It does actually work
and we get reasonable performance out of it on a modern machine.
On a PowerBook G4 I get a few MBit for TX and a few more for RX.
So it doesn't work as well as DMA (of course), but it's a _lot_ faster
than the old PIO code (only got a few kBit with that).

The limiting factor is the host CPU speed. So it will generate 100%
CPU usage when the network interface is heavily loaded. A voluntary preemption
point in the RX path makes sure Desktop Latency isn't hurt.

PIO is needed for 16bit PCMCIA devices, as we really don't want to poke with
the braindead DMA mechanisms on PCMCIA sockets. Additionally, not all
PCMCIA sockets do actually support DMA in 16bit mode (mine doesn't).

First the driver needs to block new packets from being queued for Tx.

Implement triggers inside rt2x00 itself based
on input from mac80211. This replaces the method
of using the mac80211 trigger events which do
not work for USB drivers due to the scheduling
requirement.

After this patch RT2500USB_LEDS and RT73USB_LEDS
no longer need to be tagged as broken since they
now support LED handling again without having to
check for in_atomic().

The TO_DS filter does not only depend on the FIF_PROMISC_IN_BSS flag
provided by mac80211, but also on the intf_ap_count count.
This makes sense, since when Master mode is active, we should all frames
that are send to the active AP (the device itself).

This means that when an interface is added we should force the
packet filter to be updated during the next mac80211 call of
configure_filter() to make sure the intf_ap_count field is checked.

this patch make this an extern structure, initialized at module load time.
