Move wl12xx and wl1251 modules into a new drivers/net/wireless/ti

change.

A special PLT firmware is used for calibration.
Add multiple fw support by introducing a new fw_type member,
representing the currently saved fw (the actual fw state
can be determined by wl->state).

When configuring the arp response template,
and encryption is enabled, we should add some
space and set the protected flag bit in the fc.
In order to track the encryption type, set
wlvif->encryption_type when setting an encryption key,
and reconfigure the arp response. Clear this field on
wl1271_join, as keys have to be re-configured
anyway after a join command.
Similarly, track whether QoS is configured.

WLVIF_FLAG_PSM turned to WLVIF_FLAG_IN_AUTO_PS which
marks that this vif is in AUTO PS.
WLVIF_FLAG_PSM_REQUESTED is not required as mac80211
calls op_config with CONF_PS after association.
wl12xx_config_vif() handling of CONF_PS was simplified
and cleaned up.

When compiling wl12xx for x86, there was a warning complaining about
the size of the buffer we were allocating in the stack:
drivers/net/wireless/wl12xx/debugfs.c: In function 'driver_state_read':
drivers/net/wireless/wl12xx/debugfs.c:380:1: warning: the frame size of 1040 bytes is larger than 1024 bytes

Separate the debugging macros and other definitions to a new debug.h
file. This is be needed because the sdio and spi modules don't need
to depend on the wl12xx module anymore, but still need to include
wl12xx.h. Currently they do depend on it, because of the debugging
global that wl12xx exports. A future patch will remove this
dependency.

wl->vif is appropriate only when a single vif is being used.
Instead, pass wlvif as parameter or iterate through all
the vifs (e.g. when a global configuration was changed)
Leave wl->vif only to determine whether a vif was already
added (this check will be removed as well after both the
driver and fw will support multiple vifs)

Split tx_queue_count to count per-AC skb's queued, instead of relying on
the skb-queue len. The skb queues used were only valid in STA-mode, as
AP-mode uses per-link queues.
This fixes a major regression in AP-mode, caused by the patch
"wl12xx: implement Tx watermarks per AC". With that patch applied, we
effectively had no regulation of Tx queues in AP-mode. Therefore a
sustained high rate of Tx could cause exhaustion of the skb memory pool.

To achieve maximal throughput, it is very important to react to
interrupts as soon as possible. Currently the interrupt handler wakes up
a worker for handling interrupts in process context. A cleaner and more
efficient design would be to request a threaded interrupt handler. This
handler's priority is very high, and can do blocking operations such as
SDIO/SPI transactions.
Some work can be deferred, mostly calls to mac80211 APIs
(ieee80211_rx_ni and ieee80211_tx_status). By deferring such work to a
different worker, we can keep the irq handler thread more I/O
responsive. In addition, on multi-core systems the two threads can be
scheduled on different cores, which will improve overall performance.
The use of WL1271_FLAG_IRQ_PENDING & WL1271_FLAG_IRQ_RUNNING was
changed. For simplicity, always query the FW for more pending
interrupts. Since there are relatively long bursts of interrupts, the
extra FW status read overhead is negligible. In addition, this enables
registering the IRQ handler with the ONESHOT option.
