When setting up a beacon template, the length of the beacon is
calculated with the assumption that the SKB already contains
the Tx descriptor. In the case of beacons it doesn't.
This patch undoes the damage by adding the Tx descriptor length
to the beacon length. This is safe, because the shortest possible
beacon is longer than the Tx header.

Adds an extra rt2x00 vendor request function to support register
transfers beyond the CSR_CACHE_SIZE / USB packet size limit. This
is useful for firmware uploads, beacon templates and keys, all
of which are to large to do with a single USB request.

Olivier reported a difference between the EIFS
values used in the legacy driver and the one in
the rt2x00 drivers.
In rt2x00 the value was
( SIFS + (8 * (IEEE80211_HEADER + ACK_SIZE)) )
which comes down to 314us while the legacy driver uses the value 364us
This was caused because EIFS is: SIFS + DIFS + AckTime
This patch will fix this by adding the DIFS by the above value,
and creating a SHORT_EIFS define which uses the SHORT_DIFS.

ath5k_beacon_update takes sc->lock upon entry. However, it is only
called from within ath5k_config_interface, which already holds the lock.

- disable and enable msi
- don't set D0 state of the device, it's already done by the PCI layer

Make sure that the irq is not in progress after stop. This means
two things:
- ensure the intr setting register is set by flushing posted values
- call synchronize_irq() after that
Also flush stop tx write, inform callers of the tx stop about still
pending transfers (unsuccessful stop) and finally don't wait another
3ms in ath5k_rx_stop, since ath5k_hw_stop_rx_dma ensures transfer to
be finished.
Make sure all writes will be ordered in respect to locks by mmiowb().

When signal is noisy, hardware can use all RX buffers and since the last
entry in the list is self-linked, it overwrites the entry until we link
new buffers.
Ensure that we don't free this last one until we are 100% sure that it
is not used by the hardware anymore to not cause memory curruption as
can be seen below.
This is done by checking next buffer in the list. Even after that we
know that the hardware refetched the new link and proceeded further
(the next buffer is ready) we can finally free the overwritten buffer.
We discard it since the status in its descriptor is overwritten (OR-ed
by new status) too.
