When doing a channel change, the pending URBs have to be killed
properly on calling htc_stop().
This fixes the probe response timeout seen when sending UDP traffic at
a high rate and running background scan at the same time.

ath.ko is a common module shared between ath5k, ar9170usb, ath9k and ath9k_htc.
Adding driver specific data to the shared structure would impact all the
drivers. Handling USB device recognition for devices specific to ath9k_htc
can be handled within the driver itself.
Also, AR7010 refers to the processor used in both AR9280/AR9287 based
devices. Rename the device enumerations accordingly.
While at it, check properly for the bus type when choosing the EEPROM
base address for UB95.

Do not assign the FW name to driver_info but determine
it dynamically on device probe. This facilitates adding new
firmware.

This patch simplifies URB management for transmission,
by removing the 'FLUSH' variable (which is not needed,
since we can determine if the URB has been killed by
looking at the URB status), and also handling the STOP
case properly.

hif_usb_regout_cb() frees the given URB, which is
borked by design. Use an anchor to simplify URB
management.

The maximum number of packets in a single buffer in
stream mode is 10. The driver currently uses 8 - which
caused stack corruption, in the absence of any kind
of OOB checking.
Fixing this to the correct value of 10 fixes the module
unload issue.

Use a spin lock to prevent concurrent access
to variables dealing with RX stream mode handling.
Currently, no protection is implemented - which
causes problems in RX.

This patch introduces the usage of URB anchors,
thus reducing a large amount of code dealing with
URB maintenance within the driver. The RX callback now
takes care of freeing the SKB associated with each URB.
