When building 4965 without 5000+ there were a
lot of build errors due to functions being used
that weren't even compiled in. To fix this move
some code around and only compile the HCMD code
for 5000+ series as it's not used for 4965.

Add watchdog functions for managing the Queues inside the hardware.
Normally the driver doesn't have much to do with these queues
directly, but the Ralink drivers did implement watchdog functions
for these. These watchdog functions are not triggered that often,
compared to the other watchdog functions, but I have at least
seen them trigger once or twice during a long stresstest run.

As part of the queue refactoring, the rt2x00lib_toggle_rx
can be removed and replaced with the call directly to
the set_device_state callback function.
We can remove the STATE_RADIO_RX_ON_LINK and
STATE_RADIO_RX_OFF_LINK, as it was only used for
special behavior inside rt2x00lib rather then the
drivers.

This patch fixes a few shortcomings in the tx path.
* move temp. ampdu_[ack]_len out of txinfo->pad.
* fix WARN_ON from tx.c:line 300 when tx_ampdu_queue
fails to queue the frame.
* In tx_prepare, we already have a local pointer
to the station's ieee80211_sta struct.
* remove a second !sta check, tx_prepare already takes
care of that.

crypto_free_cipher() is a wrapper around crypto_free_tfm() which is a
wrapper around crypto_destroy_tfm() and the latter can handle being passed
a NULL pointer, so checking for NULL in the
ieee80211_aes_key_free()/ieee80211_aes_cmac_key_free() wrappers around
crypto_free_cipher() is pointless and just increase object code size
needlesly and makes us execute extra test/branch instructions that we
don't need.
Btw; don't we have to many wrappers around wrappers ad nauseam here?
Anyway, this patch removes the redundant conditionals.

The BSSID register shouldn't be set in AP mode on some older devices (like
rt73usb) as it breaks hw crypto on these. However, rt2800 devices explicitly
need the BSSID register set to the same value as our own MAC address (only
in AP mode).
Hence, don't set the BSSID from rt2x00lib but move it down into rt2800 to
avoid problems on older devices.
This fixes a regression (at least for rt73usb) and avoids a new regression
for rt2800 devices in 2.6.36.

Implement a basic flush callback function, which simply loops
over all TX queues and waits until all frames have been transmitted
and the status reports have been gathered.
At this moment we don't support dropping any frames during the
flush, but mac80211 will only send 'false' for this argument anyway,
so this is not important at this time.

All rt2x00 devices used the same Tx and Rx ring size (24 entries) till
now. Newer devices (like rt2800) can however make use of a larger TX and
RX ring due to 11n capabilities (AMPDUs of size 64 for example).
Hence, bring rt2x00 in sync with the legacy drivers and use the same TX
and RX ring sizes. Also remove the global defines RX_ENTRIES, TX_ENTRIES,
BEACON_ENTRIES and ATIM_ENTRIES and use per driver values.
That is 24 entries for rt2400pci, 32 entries for rt2500pci, rt2500usb,
rt61pci and rt73usb and 128 (RX) and 64 (TX) for rt2800pci and rt2800usb.

The current ath9k tx queue handling code showed a few issues that could
lead to locking issues, tx stalls due to stopped queues, and maybe even
DMA issues.
The main source of these issues is that in some places the queue is
selected via skb queue mapping in places where this mapping may no
longer be valid. One such place is when data frames are transmitted via
the CAB queue (for powersave buffered frames). This is made even worse
by a lookup WMM AC values from the assigned tx queue (which is
undefined for the CAB queue).
This messed up the pending frame counting, which in turn caused issues
with queues getting stopped, but not woken again.
To fix these issues, this patch removes an unnecessary abstraction
separating a driver internal queue number from the skb queue number
(not to be confused with the hardware queue number).
It seems that this abstraction may have been necessary because of tx
queue preinitialization from the initvals. This patch avoids breakage
here by pushing the software <-> hardware queue mapping to the function
that assigns the tx queues and redefining the WMM AC definitions to
match the numbers used by mac80211 (also affects ath9k_htc).
To ensure consistency wrt. pending frame count tracking, these counters
are moved to the ath_txq struct, updated with the txq lock held, but
only where the tx queue selected by the skb queue map actually matches
the tx queue used by the driver for the frame.

Current 8187B initialization misses anaparam registers restore after

right after chip reset (to be on the safe side, as it makes sure we
restore all ANAPARAM registers).

The GNTSel bit should only concern pci devices by looking at RTL8180
spec, which is not the case of 8187B. Also testing shows that trying to
set this bit fails, a subsequent read from the register after trying to
set it shows that the bit isn't set, seems the hardware ignores it,
