libertas: switch lbs_cmd() to take a callback function pointer
All existing code which sends commands is set up to have some function
called with the results, not to get data back. It's more versatile this
way, and providing it with a callback function which involves memcpy()
is hardly difficult.

libertas: endianness fixes
Recently I found that that sparse by default doesn't endianness
checks. So I changed my compilation habit to be
make modules C=1 SUBDIRS=drivers/net/wireless/libertas
CHECKFLAGS="-D__CHECK_ENDIAN__"
so that I get the little-endian checks from sparse as well. That
showed up a good bunch of problems.

libertas: implement new scanning logic
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 :-)

libertas: handy function to call firmware commands
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:

gianfar driver: eliminate compiler warnings and unnecessary macros
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.
