This changes the code that is used for scanning and makes it hopefully
easier to understand:
* move function into logical blocks
* create a bunch of lbs_scan_add_XXXX_tlv() functions, that
help to create the TLV parameter of CMD_802_11_SCAN
* all of them are now called from the much simpler lbs_do_scan()
* no **puserscancfg double-pointers :-)

I wondered about junk bytes at the end when using "lbsdebug +hex +host"
until I noticed that firmware for the CF card sends my extranous bytes.
It says "I have 20 bytes", I take 20 bytes, but the last 8 bytes of this
are just data junk.
Also, in the new lbs_cmd() where was a size miscalulation
that made itself clear after fixing this bug.

Using an arbitrary firmware command was actually very painful. One
had to change big switch() statements in cmd.c, cmdresp.c, add
structs to the big union in "struct cmd_ds_command" and add the
define for the CMD_802_11_xxx to the proper place.
With this function, this is now much easier. For now, it implements
a blocking (a.k.a. CMD_OPTION_WAITFORRSP) way where one deals directly
with command requests and response buffers. You can do everything in
one place:

This patch eliminates the warning of unused return values when the driver
registers it sysfs files. Now the driver will print an error if it is
unable to register the sysfs files.
It also eliminates the macros used to wrap the DEVICE_ATTR macro and the
device_create_file function call. The macros don't reduce the number of
lines of source code in the file and the name munging makes is so that
cscope and friends don't see the references to the functions. It's better
to just call the kernel API directly.
While we're at it, the DEVICE_ATTR instances have been moved down to
be grouped with the functions they depend on.

The BCM94311MCG rev 02 chip has an 802.11 core with revision 13 and
has not been supported until now. The changes include the following:
(1) Add the 802.11 rev 13 device to the ssb_device_id table to load b43.
(2) Add PHY revision 9 to the supported list.
(3) Change the 2-bit routing code for address extensions to 0b10 rather
than the 0b01 used for the 32-bit case.
(4) Remove some magic numbers in the DMA setup.
The DMA implementation for this chip supports full 64-bit addressing with
one exception. Whenever the Descriptor Ring Buffer is in high memory, a
fatal DMA error occurs. This problem was not present in 2.6.24-rc2 due
to code to "Bias the placement of kernel pages at lower PFNs". When
commit 44048d70 reverted that code, the DMA error appeared. As a "fix",
use the GFP_DMA flag when allocating the buffer for 64-bit DMA. At present,
this problem is thought to arise from a hardware error.
