The commit below changed the semantics of rt2x00_check_rev so that it no
longer checked the bottom 4 bits of the rev were non-zero. During that
conversion this part of the check was not propogated to the rt2500usb
initialisation.

rt2x00: Simplify rt2x00_check_rev
Without this check rt73 devices are miss recognised as rt2500 devices and
two drivers are loaded. Preventing the device being used. Reinstate this
check.

Remove the input_polldev from rt2x00 and replace it with
the rfkill interface offered by the wiphy structure. This
simplifies the entire rfkill handling in rt2x00 and allows
us to remove the CONFIG_RT2X00_LIB_RFKILL option and always
enables rfkill capabilities.

Within mac80211, we often need to copy the rx status into
skb->cb. This is wasteful, as drivers could be building it
in there to start with. This patch changes the API so that
drivers are expected to pass the RX status in skb->cb, now
accessible as IEEE80211_SKB_RXCB(skb). It also updates all
drivers to pass the rx status in there, but only by making
them memcpy() it into place before the call to the receive
function (ieee80211_rx(_irqsafe)). Each driver can now be
optimised on its own schedule.

Some hardware require L2 padding between header and payload
because both must be aligned to a 4-byte boundary. This hardware
also is easier during the RX path since we no longer need to
move the entire payload but rather only the header to remove
the padding (mac80211 only wants the payload to be 4-byte aligned).

By exporting the register base, and word size to userspace
through debugfs it will be easier to create scripts which
parse the register information. This makes debugging and
register dumps information easier.
This will break my previous scripts which dumped and parsed
all information, but since this is only for debugging purposes
this change should not be a problem.
Dumpfiles created with the old version can be easily manually
edited to make them compatible with this new approach, which
means there will be no problems comparing dumps from the
different versions either.
Also be more consistent with using tabs to seperate different
fields.

Software antenna tuning is broken because of an function
ordering problem during rt2x00link_tuner().
rt2x00link_precalculate_signal()
rt2x00leds_led_quality()
rt2x00lib_antenna_diversity()
rt2x00link_precalculate_signal() will reset the quality TX/RX counters,
however rt2x00lib_antenna_diversity() requires the RX counter to
see what RSSI value must be used for a particular antenna.
We can't change the ordering since rt2x00lib_antenna_diversity() might
reset other statistics which are needed by the function called earlier.
Move the reset of the quality TX/RX counters into a seperate function
and move the call to after rt2x00lib_antenna_diversity().

The word_base is in bytes instead of word index number,
this means that when using it, it should be transformed into
a word index first.
Otherwise RF register reading will fail through debugfs since
we would start reading 4 words starting with word 4 (which is the last
valid word for RF).

The only way rf_write() can be called with word 0 is
when the user sends the wrong word index through debugfs.
However the values which are send through debugfs are
validated using the RF_BASE and RF_SIZE macro values,
the most logical solution is to increase RF_BASE with 4
and decrease RF_SIZE with 4 (RF_SIZE has always been
1 word too big)
