Move wl12xx and wl1251 modules into a new drivers/net/wireless/ti
directory.  Add a TI WLAN Kconfig option and Makefile to support this
change.

This module has been causing more trouble than being useful.  It only
tests the SDIO speed by connecting to the wl12xx chip and does some
throughput calculations.  It is an ugly quick hack and, if we really
want to have it as part of wl12xx we need to clean it up and implement
it properly.

A tarball of the code has been created and posted here, with some
instructions:

Due to some changes in PM in recent kernels, the sdio_test module has
been broken for a while.  This patch fixes the code that powers the
card on and off.

Also made some small indentation fixes in the Makefile.

Change some file names and Kconfig settings so that this new module matches
the new way of using wl12xx instead of wl1271.

Also fix SDIO power enabling and disabling to match the latest way of doing
it.

This module enables individually generating RX and TX traffic
over the SDIO bus on which the WL1271 chipset is connected.
This is required to perform RF interference testing.

The module takes 2 module parameters 'rx' and 'tx'.

To generate RX traffic:
	modprobe wl1271_sdio_test rx=1
To generate TX traffic:
	modprobe wl1271_sdio_test tx=1

To generate both RX & TX traffic, set both rx and tx to 1.

You can change the testing configuration at runtime by changing
the rx & tx values at /sys/modules/wl1271_sdio_test/

To stop testing simply unload the module.

wl1271 driver is under heavy development but on the other hand the older
wl1251 driver is currently considered more as a legacy driver. To make it
easier to develop wl1271 features move wl1251 to it's own directory,
drivers/net/wireless/wl1251.

There are no functional changes, only moving of files. One regression
is that Kconfig won't be updated automatically and user needs to enable
wl1251 manually with an older config file.

The scanning code is going to get a bit more complex, with proper support for
active/passive scans together with 2.4GHz and 5GHz.  In the future, also a
new type of scan (periodic scan) will be added.  When all this is
implemented, the code is going to be much more complex, so we'd better
separate it into a separate file.

This patch doesn't have any impact on functionality.

wl12xx is a driver for TI wl1251 802.11 chipset designed for embedded
devices, supporting both SDIO and SPI busses. Currently the driver
supports only SPI. Adding support 1253 (the 5 GHz version) should be
relatively easy. More information here:
